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

Due to patch fuzz, it was applied again, so the same code sequence was
repeated twice. Not sure if that caused any bugs, but certainly wasn't
the right thing to do.

Fix an internal compiler error on PPC from building a specific test:
$ $CC -S 7d-02.c
7d-02.c: In function รข:
7d-02.c:11:5: internal compiler error: in copy_to_mode_reg, at explow.c:612
vec_st(v, i*16,p);
^~~~~~
The failure appears to happen on all optimizations levels as well.

Whenever "-mno-sse" is used, "-mfpmath" should be set to 387.
The test case should be modified accordingly as below:
/* { dg-additional-options "-mno-sse -mfpmath=387 " { target { i?86-*-* x86_64-*-* } } } */

The static PIE patch was updated by Juro Bystricky <juro.bystricky@intel.com>
to work with gcc 7.3.
This update from the stable gcc 7 branch includes the retpoline
functionality which is useful to assist with recent security issues.
Two backported patches were dropped as they're included in 7.3.
