That's the way it should be, but not the way it is. Since the switch
from Libc5 to Glibc, it is always called libc.so.6, and the ABI does
break on each release (in fact, two compilations of the same version
with different flags have incompatible ABIs). When asked about this,
the developers say "it's up to the distro maintainers to take care of
ABI issues" (very much like the kernel people say :( ).

It's been a while since I messed with Glibc compilation, but that's a
possibility.
