GLib 1.x is incredibly obsolete and GLib 2.x is built using Meson
not autotools, so we can remove the GLib entries from the site files.
Also fix a few copy/paste typos where glib_ was used incorrectly, for example:
ac_cv_sizeof_ptrdiff_t=${glib_cv_sizeof_ptrdiff_t=4}
The glib_cv_ should be ac_cv_.

off_t is always 64bit on musl regardless of 32bit or 64bit
architectures. autoconf has AC_SYS_LARGEFILE to detect correct off_t
size but it only work with glibc since it defines feature macros
_FILE_OFFSET_BITS=64 and _LARGEFILE_SOURCE but these macros are
not used on musl headers.

This fixes bash using its own broken getcwd() during cross compiling
The configure script assumes that your getcwd() function is broken.
Which then makes bash use it's own getcwd() implementation, which
doesn't work if the path to the current directory
contains bind mounts in its paths. This shows up as:
Fixes errors on musl images like
shell-init: error retrieving current directory: getcwd: cannot access parent directories: Bad file descriptor

glibc 2.32 has deprecated sys_siglist [1]
since no is default for musl as well, therefore elevate it to common

This coreutils (gnulib) test tests for various bugs that only
exist in ancient versions.
It defaults to assuming buggy behaviour with its own implementation
when cross-compiling.
musl and recent glibc (2.29) are not affected.

autoconf has a test for strtod(), which assumes non-working
when cross-compiling, but it does work in both musl and
recent glibc.
coreutils (gnulib) does some additional tests on top of that,
but assumes working glibc when >= 2.8 when cross compiling.
It doesn't know about musl where the additional tests also
work, though.

As per coreutils' (gnulib's) autotools test, nanosleep()
misbehaves on glibc (2.29), and works fine on musl.
During cross-compile, recent coreutils assume brokenness
when compiling for linux, which pessimises musl.
Set the correct result for musl, and for coherency reasons,
also specify the result for glibc.

recent coreutils (gnulib) assume yes when cross-compiling
for gnu (glibc), but don't know about musl.
For coherence, just set the result to yes for both.
Note that the old coreutils (from meta-gplv2) doesn't
assume anything and instead that recipe hard-codes to yes.
So behaviour with yocto when using meta-gplv2 is actually
better than when using the latest version (when using musl).
This patch rectifies this shortcoming.

This coreutils (gnulib) test checks for an abort() that existed
in glibc before 2.4.90-10 (in 2006) in certain conditions.
Neither libraries exhibit this problem today.

In glibc, getcwd() handles long file names properly, on
musl, getcwd() only works up to PATH_MAX directory depths.
Configuring the autotools (gnulib) test result here allows
coreutils to compile more optimised code for both platforms,
rather than being pessimistic and re-implementing everything
itself.
The difference in behaviour is because both do the kernel
getcwd syscall (which only supports up to PATH_MAX), but
glibc implements fallbacks for longer paths, while musl
doesn't.

This is the cache variable used by AC_FUNC_MMAP, which is possibly one of the
worst autoconf macros to exist.
Apart from being a runtime test which silently claims that mmap() is broken when
cross-compiling, this is basically to verify that mmap() actually works, because
SVR4.0 (released 1988) was broken. Thirty years later, everyone has a working
mmap().
common-glibc already has an assignment, so add a corresponding assignment to
common-musl and remove it from the machine-specific files.
