Yes.  It can vary per executable.  The ldd command shows you which
libraries are used by an executable.  On a bo system, I get

$ ldd /bin/ls
        libc.so.5 => /lib/libc.so.5.4.33

This is using libc5

On a hamm system, I get

$ ldd /bin/ls
        libc.so.6 => /lib/libc.so.6 (0x4000f000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

This is using libc6, and the ld-linux.so.2 library.

A hamm system is libc6, but you can run libc5 executables as wel.  For
them to work you need to install some packages from hamm's oldlibs
section.
