libssp is implemented fully in glibc as well as in musl
so we really do not need the gcc version of this library
except may be for mingw, where we keep it enabled anyway
gcc in OE is built with the knowledge that C library
already provides libssp implementation, we should therefore
not need the gcc implementation of same.
libssp_nonshared piece is a detail which is needed when gcc
is the compiler, in glibc this is part of libc_nonshared.a
already and libc_nonshared.a is linked always when linking
with -lc becuase libc.so in glibc is actually a linker script
GROUP ( /usr/lib/libc.so.6 /usr/lib/libc_nonshared.a AS_NEEDED ( /usr/lib/ld-linux-x86-64.so.2 ) )
which automatically links in the needed runtime bits, this however
is not the case for musl, where core SSP APIs are implemented in full
but compiler specific runtime isn't, for this we add a new package
called libssp_nonshared which generate the needed runtime stub
and gcc is already carrying patch to link to libssp_nonshared.a
on musl
This should fix a long standing problem where static PIE executable
were not buildable with OE since it was conflicting SSP implementation
one from C library and the other one from gcc and we end up with
duplicate symbol errors during linking.
Backport a patch from trunk which enhances enable|disable-libssp
to not only disable building libssp but also not emit the gcc
specs to use it for subsequent linking when stack-protector options
are used on compiler cmdline

Remove various build host references from packages:
libstdc++
libstdc++-staticdev
gcc-runtime-dbg
The references are removoved by correctly setting various compiler
-fdebug-prefix-map settings. There are two main issues:
The default DEBUG_PREFIX_MAP variable references WORKDIR, however,
gcc sources are in a shared folder (work-shared)/
Additionally, DWARF info seems to store symlink names but gcc
seems to resolve symlink names referenced in -fdebug-prefix-map.

Backport a patch to fix miscompilation on mips64.
We've observed strange behaviour of `systemctl status <xxx> on qemumips64.
The output of the command is like `systemctl show <xxx>', which is incorrect.
The problem is due to the miscompilation of gcc for mips64 platform, thus

Use ucontext_t not struct ucontext in linux-unwind.h files.
Current glibc no longer gives the ucontext_t type the tag struct
ucontext, to conform with POSIX namespace rules. This requires
various linux-unwind.h files in libgcc, that were previously using
struct ucontext, to be fixed to use ucontext_t instead. This is
similar to the removal of the struct siginfo tag from siginfo_t some
years ago.

Under some rare circumstances we may end up with GCC segmentation fault.
This was observed with versions of sysmacros.h, which contain macros
with embedded warning messages :
When trying to actually display the warning, we may end up with a segmentation
fault instead. The reason is the actual warning message gets parsed (the text is
unquoted) and words in the message such as "not", "and" etc. are interpreted as
operators CPP_NOT, CPP_AND. When the time comes to display the warning, the code
uses wrong structure to access the "name" corresponding to the operators.

If we used -fuse-ld gcc option, then it does not work
ending in
collect2: fatal error: cannot find 'ld' compilation terminated.
This is because we are not creating proper symlinks for BFD
and Gold linker in gcc installation
Secondly, we end up with dangling fortran compiler symlinks
if fortran is not enabled when confguring gcc, therefore
create these symlinks only when fortran support is enabled
in gcc

The change to link libssp_nonshared.a only for musl was to move
spec file changes to config/linux.h under a conditional when
DEFAULT_LIBC == LIBC_MUSL which worked fine for all but ppc
since gcc for ppc provided its own linux.h overrides which are
used. This patch duplicates the change in those headers too

"yocto-compat-layer.py --machines" showed that shared packages like
gcc-cross-powerpc64 have a sstate signature that depends on
TUNEFLAGS. As a result, there are unnecessary rebuilds and potential
conflicts in a multiconfig.
That's due to the way how TARGET_ARCH is set. Richard Purdie suggested
setting TARGET_ARCH[vardepvalue] as fix, which works. It would be
shorter to do that in cross.bbclass instead of repeating the relevant
line in different recipes, but Richard was concerned about potential
side-effects in other usages of cross.bbclass.
TARGET_GOARM as used in go.inc is still causing signature differences
for go-cross-powerpc64 and machines b4420qds-64b and p5020ds-64b. This
needs further investigation.

We've had a lot of users running into RSS issues where -initial recipes
were being installed into sysroots alongside their counterparts and
causing overlapping files issues.
In general this was through do_build dependencies. Such dependencies are
bad in general and I'd encourage people to compare the taskgraphs with
using a more specific dependency like do_populate_sysroot, do_image_complete
or do_deploy as often the more specific dependency will result in a much
cleaner build.
Regardless, we don't want -initial dependencies getting in the way like
this and there are cases a do_build dependency could make sense.
Deleting the do_build task in these cases makes sense since this is not
a build "endpoint" we'd ever want a user to use, its a behind the scenes
piece of bootstrappping.
Unfortunately to make this work, we need a newer bitbake version which
has a bitbake bug fixed.
