-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.
-
-Forward ported to gcc 4.7.3

-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.

-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.
