Fixed configure.ac to use $CC instead of 'gcc' for version checking.

This has caused problems in settings where the desired compiler
isn't the system bundled GCC (as in Mac OS X Mavericks builds where
we have been using specific versions of GCC).

Review #14164 is re-enabled for $(CC) instead of 'gcc' and lets us
compile with GCC 4.8 on Mavericks instead of down-grading to 4.7.
