We can now drop the cross-compile check in jpeg/Makefile if you are 
going to make this conditional on the compiler version. The only reason 
we added this was because our ppc compiler is only 4.1.2

So one thing I am confused about is the required gcc version. We had 
bumped it up to 4.3 because of this no-clobber usage. But now that use 
of that option is conditional does that mean we can lower the required 
gcc version again?
