GCC and glibc are separate projects, built and installed separately,
so if you install GCC that doesn't install glibc.

GCC uses the system's C library, so on GNU/Linux it uses glibc because
that's what's available, but on Solaris it uses the Solaris libc.

glibc is probably not even installed at all.
