PowerPC glibc patches

[Fernandes, Joao Moreira (EXT-Other PT/Amadora)]

While trying to build a toolchain for a PowerPC system with gcc 4.8.1, binutils 2.22 and glibc 2.8, I faced some difficulties. Firstly, patch glibc/2.9/600-recent-binutils.patch also had to be applied to glibc 2.8; secondly, gcc 4.8 dropped -mnew-mnemonics/-mold-mnemonics options, so I had to remove -mnew-mnemonics from sysdeps/powerpc/Makefile - this is safe as -mnew-mnemonics is gcc's default since the early 90's - and this applies to glibc versions < 2.17; lastly, the patch from https://sourceware.org/ml/crossgcc/2008-10/msg00010.html had to be applied. A set of patches addressing all these issues is attached.

After these changes I was able to successfully build the toolchain (config file attached). Enabling "Disable symbols versioning" in the "C Library" section made the build fail, but I didn't have the time to investigate why.
