[Libvir] don't clobber user-specified CFLAGS
Building libvirt with CFLAGS=-g doesn't work as expected: gcc runs
without -g. That was due to the following assignment that gives CFLAGS
the value of an undefined variable.
2007-03-23 Jim Meyering <jim(a)meyering.net>
* acinclude.m4: Remove bogus CFLAGS=$undefined_var assignment that
would clobber any CFLAGS setting from e.g., ./autogen.sh CFLAGS=-g.
