Use the patch by Carl Miller <chaz@energoncube.net> for powerpc, with
some minor modifications. Changed *os_uclibc to *os_linux_uclibc since
at some point we might support other platforms. Also updated to 3.3.3.

Subject: [trunk + 3.4-branch RFA] don't use empic relocs for mips-linuxeh
This patch changes mips-linux to avoid using embedded-pic relocs for
its eh data. (Support for generating these for new code is removed in
current binutils srcs.)
Relating to this, previously, mips-linux and mips64-linux would use
different representations for their EH data (even for mips64-linux o32
abi), due to the mips64-linux n32/64 BFDs not supporting the
embedded-pic relocs. This was a bug.
For more explanation, see the thread of the URL quoted in the comment
in linux.h.
Tested the same w/ sources of about a week ago for c/c++ for
mips-linux (native) before/after. Also verified .o compatibility
before/after just to be sure.
I'd like this approved for the branch as well, so 3.4.1 will work
nicely w/ the next major binutils release.
thanks,
chris

The 30_all_gcc34-arm-ldm-peephole.patch from Debian was conflicting
