Folks,

This hunks seems not to be POSIX shell compliant. Both vars are set for
me on HP-UX because the expansion is incomplete. According to [1] it has
to be $(GCC:+..} and not $(GCC+..}. I have changed ./configure locally
and it works with /bin/sh.
I assume that this should also work on any other POSIX compliant shell.
