Comment:
> It seems that we're bumping the revision for packages to force them to re-build with the new gcc/glibc version. However; how do we know which packages should be rebuilt and which shouldn't?

libtool and mk-configure hard code gcc paths and other information so they need to be rebuilt.

> After merge, will there still be packages that are built against the old glibc version but at runtime will link against the new installed glibc version?

Yes, that is by design. (although this is gcc, not glibc)
