The monotonically increasing revision ids need to be globally unique, so they should
only identify commits that were committed to the upstream repo to its master or
releases/gcc-N branches. The alias could print something even for private branches
or vendor branches etc., but if such an identifier is then used publicly, it will
refer to something else.

* gcc-git-customization.sh: Verify the id to be printed is ancestor of
the corresponding remote release branch (or master), otherwise print
nothing.
