Subject: [svn-r10132] Purpose: Bug fix

Description:
When C flags are passed in using $CC variable, this can confuse test
commands in configure (for instance, CC='pgcc -tp k8-32').

Solution:
Previous solution didn't entirely solve problem.  Wrote a sed snippit
to strip flags from $CC for purposes of test in configure.

Platforms tested:
mir (just a configure bug)
