GCC-4.6 update for precise

[Matthias Klose]

I'm planning to update GCC-4.6 on Feb 10, to be built over the weekend. The 
update includes the Linaro GCC 4.6-2012-02 release, and updates from the FSF branch.

Changes in the Linaro GCC 4.6-2012-02 release include

  - bug fixes to the vectorizer
  - support for cortex-a7
  - support for cortex-a15 tuning
  - fixes for ICE's, partially already available in the
    Ubuntu gcc-4.6 packages.
  - Complete release notes:
    https://launchpad.net/gcc-linaro/4.6/4.6-2012.02

Changes in the FSF updates consist of wrong-code fixes, ice-on-valid-code fixes, 
target fixes, and some diagnostic fixes.  Tested and regression-tested on amd64 
and i386.

Packaging changes are limited to the cross-compiler packages.
