Update build-many-glibcs.py for GCC move to git.

Browse Source 
This patch updates build-many-glibcs.py for the move of GCC to git,
teaching it to do the initial checkout from git, to replace an SVN
checkout with a git one if --replace-sources is used, and to get the
commit identifier from a git checkout after updating it.
