crosstools: Using CC

[Neal H. Walfield]

Hi,

I tried to use crosstools to generate a tool chain for x86_64 using
gcc-3.3 (not gcc) by running:

	CC=gcc-3.3 sh demo-x86_64.sh

On my Debian installation, gcc is version 2.95.  There are packages
available to use later gccs and these are installed as gcc-VERSION.

The above failed because there are two places in crosstools.sh that
ignore CC and use gcc.  Once I corrected these, it worked fine.  I
haven't throughly read the source code to know if this is the correct
general fix, however, it does work for me.  

Thanks,
Neal
