http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00269.html
On glibc the libc.so carries a copy of the math function copysignl() but
on uClibc math functions like copysignl() live in libm. Since libgcc_s
contains unresolved symbols, any attempt to link against libgcc_s
without explicitely specifying -lm fails, resulting in a broken
bootstrap of the compiler.

View File

Allow C99-depending features of libstdc++ with uClibc
The libstdc++ code is fairly restrictive on how it checks for C99
compatibility: it requires *complete* C99 support to enable certain
features. For example, uClibc provides a good number of C99 features,
but not C99 complex number support. For this reason, libstdc++
completely disables many the standard C++ methods that can in fact
work because uClibc provides the necessary functions.
This patch is similar and highly inspired from
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
a way that doesn't involve changing the configure.ac script, as
autoreconfiguring gcc is complicated. It simply relies on the fact
that uClibc defines the __UCLIBC__ definition.

Subject: [PATCH] PR other/56780
* libiberty/configure.ac: Move test for --enable-install-libiberty
outside of the 'with_target_subdir' test so that it actually gets
run. Add output messages to show the test result.
* libiberty/configure: Regenerate.
* libiberty/Makefile.in (install_to_libdir): Place the
installation of the libiberty library in the same guard as that
used for the headers to prevent it being installed unless
requested via --enable-install-libiberty.

libiberty: fix --enable-install-libiberty flag [PR 56780]
Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted. So we end up initializing properly
at the top only to reset it at the end all the time.

Add musl support to gcc
This patch comes from the musl-cross project at
https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
* the config.sub modifications have been removed, because Buildroot
already overwrites all config.sub with a more recent config.sub
that has musl support.
* change to ensure that a dummy dynamic linker path
MUSL_DYNAMIC_LINKER<foo> is defined for all architectures,
otherwise building gcc for architectures not supported by musl was
causing build failure. Bug reported upstream at
https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
* change the USE_PT_GNU_EH_FRAME logic to keep the existing gcc logic
and only add the musl one as an addition, not as a replacement. Not
doing this breaks C++ exception handling with glibc, because
USE_PT_GNU_EH_FRAME doesn't get defined due to the configure script
not testing dl_iterate_phdr() on any system except Solaris.
