[arch-dev-public] gcc-4.6.0 toolchain in [testing]

[Allan McRae]

The gcc-4.6 toolchain rebuild has been uploaded to [testing]:

gcc-4.6.0-1:
   - major upstream update.  See http://gcc.gnu.org/gcc-4.6/changes.html
   - new dependency - cloog built with isl backend (replaces cloog-ppl)
   - remove elfutils dep (no longer needed)
   - clean-up of configure options
   - soname bump libobjc.so.2 -> .3
   - package gcc-go frontend
     - please test calling C/C++ code, please report results with and 
without libffi installed

linux-api-headers-2.6.38.1-1:
   - update to latest version

binutils-2.21-6:
   - new upstream snapshot from 2.21 branch
   - remove patch included upstream

glibc-2.13-5:
   - patch futex issue rather than disabling it

libtool-2.4-3:
   - gcc version bump rebuild


Test suite results can be seen at 
https://wiki.archlinux.org/index.php/User:Allan/Toolchain .  There are a 
few new failures in the gcc  and binutils testsuites.  Most appear 
unimportant, but I will investigate further before I consider moving 
this to [core].  I expect an update to binutils with quite a few 
backports soon (which may fix some of the gcc lto issues) and I will 
probably need to grab an updated gcc snapshot in a couple of weeks anyway...

Note that I have not done the small libobjc rebuild yet so if you are 
using gnustep then you might want to hold off updating for a bit.
