Re: configure does not honor CC when testing for -mcmodel=large

[Seth Goldberg]

 Ok, setting TARGET_CC to gcc-4.3.2 works around this.  My assumption was that 
CC was the right environment variable (technically, it is, since I'm not 
"cross-compiling".  This going back to the core problem of all autoconf 
detecting Solaris as i386-pc-solaris and not x86_64-pc-solaris.
