gcc: Add --enable-linker-build-id

See https://fedoraproject.org/wiki/Releases/FeatureBuildId for the
benefits this brings.  As far as I can tell from searching the
discussion archives, there doesn't appear to be a reason not to enable
this, and the benefits are real.

Both the Red Hat Enterprise Linux 6, all Fedora, and Ubuntu Quantal
GCC builds are configured with this on.  I plan to use it in
gnome-ostree.
