Only build with -g CFLAGS/LDFLAGS if using --enable-debug.
Add --optflags to allow overriding the default optimization
level added to CFLAGS.
This is a first draft of coming up with a patch I could potentially
push upstream based on much cruder local patches to do something
similar. I'm trying to eliminate having to patch the configure
script.
Comments?
