[4.7 PATCH]: Backport 'gcc_update explicit use of "svn"'

[Uros Bizjak]

Hello!

Attached patch backports 'gcc_update explicit use of "svn"' patch [1]
to 4.7 branch.

Without this patch, contrib/gcc_update command produces corrupted
gcc/REVISION on my F20 system.

        Backport from mainline
        2012-05-09  David Edelsohn  <dje....@gmail.com>

        * gcc_update: Use $GCC_SVN to retrieve branch and revision.

Bootstrapped on x86_64-pc-linux-gnu and committed to 4.7 branch.

Uros.
