pass CFLAGS to gcc configure as env vars, not on command line 

old versions of gcc, such as 4.2.1 which I'm in the process of adding
support for, have broken configure scripts that do not accept
variables on the command line and instead interpret them as the target
name. the easiest solution is just passing these in the environment.
