+Subject: [PATCH 4/6] [PATCH][clang] Prefer gcc toolchains with libgcc_s.so
+ when not static linking libgcc
+
+Fedora ships cross-compilers on all platforms, so a user could end up
+with a gcc x86_64 cross-compiler installed on an x86_64 system. clang
+maintains a list of supported triples for each target and when all
+else is equal will prefer toolchains with triples that appear earlier
+in the list.
+
+The cross-compiler triple on Fedora is x86_64-linux-gnu and this comes
+before the Fedora system compiler's triple: x86_64-redhat-linux in
+the triples list, so the cross compiler is always preferred. This
+is a problem, because the cross compiler is missing libraries, like
+libgcc_s.so, that clang expects to be there so linker invocations
+will fail.
+
+This patch fixes this by checking for the existence of libgcc_s.so
+when it is required and taking that into account when selecting a
+toolchain.
