When converting gcc to the package infrastructure, a specific thing
for PowerPC was forgotten: applying the conditional patch
powerpc-link-with-math-lib.patch.conditional. This breaks the build of
some PowerPC toolchains, with failures such as:
<http://jenkins.free-electrons.com/job/buildroot/./config=qemu_ppc_virtex_ml507_defconfig/ws/output/host/usr/lib/gcc/powerpc-buildroot-linux-uclibc/4.7.3/../../../../powerpc-buildroot-linux-uclibc/lib/libgcc_s.so.1>: undefined reference to `copysignl'

Anyone knows why we have this conditional patch? Can't it be made a
normal patch, with the appropriate modifications? Why isn't that
upstream since all those years?
