Yann,

Unfortunately I have to use Outlook (company policy...) and I'm
terrible with it, so sorry about the mess. I'm also unable to use
patchbomb in this setup, so I'm inlining the patch bellow.

Cheers,
JoÃo

libc/glibc: various powerpc glibc fixes

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 of all glibc
versions < 2.17 (this is safe as -mnew-mnemonics is gcc's default since the
early 90's); lastly, the patch from
https://sourceware.org/ml/crossgcc/2008-10/msg00010.html had to be applied.
This patch addresses all mentioned issues.

Your patches are unusable because they are attached as base64-encoded
parts, which makes them unusable.

Please, have a look at:
    docs/7 - Contributing to crosstool-NG.txt
    docs/C - Misc. tutorials.txt

for example on how to ciontribute changes to crosstool-NG.

Yann E. MORIN.
