-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.

-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.
-

-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.

+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.

+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.

+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.
