gcc: Moving the arch=loongson2f to the current platform approach
Merge branch 'pi-stdenv-updates' into stdenv-updates

This adds raspberry pi support. I've almost tested all.

Should fix https://github.com/NixOS/nixpkgs/issues/234
coreutils: update to 8.20. They didn't build in i686 here.

Here is the error:
set-mode-acl.c: In function 'qset_acl':
set-mode-acl.c:72:6: error: #error Must have acl_delete_def_file (see POSIX 1003.1e draft 17).
Setting coreutils to 8.20 for linux, 8.19 for darwin

As Eelco noted in 0ecd1f62c799dffbdbd4bc1ba8120bfb4a4c7a6f,
Darwin can't build 8.20. But linux can't build 8.19 now.
coreutils: I forgot a file in the prev commit
coreutils: fixing parenthesis on if/then

I'll never get it. This commit is suggested by Eelco, saying
the old parentheses were wrong.
gmp-5.x: update from 5.0.5 to 5.1.0
gawk: update to 4.0.2
Merge branch 'master' into stdenv-updates.
Fixing nettools with headers >=3.6 (no more strip)

I remove the strip (Metricom radio) support
ffmpeg: show vdpauSupport to the world
xbmc: add version 11
gmp: Adding more urls for 5.1.0

It worked some days ago, but gnu mirrors seem to have removed gmp 5.1.0
gtk2: a minor update
Merge branch 'master' into stdenv-updates.
gmp: version 5.1.0 has the cpu-id patch applied already
gmp: switch default version back to 5.0.5

The 5.1.0 version breaks the build of virtually every package that uses the C++
wrappers for gmp (such as mpfr, ppl, etc).
coreutils: I think I fix the evaluation, which failed for darwin.
gmp: add back the cpuid patch to 5.0.5

it was lost during 5.0.5 -> 5.1.0 -> 5.1.0 w/o patch -> 5.0.5 w/o patch
buildNativeInputs -> nativeBuildInputs
