platform darwin 8 { configure.compiler gcc-4.0 }

[Ryan Schmidt]

These lines in a portfile are useless now, right?

platform darwin 8 {
	configure.compiler gcc-4.0
}

Ever since default compilers were set in MacPorts base, gcc-4.0 is  
the default compiler on darwin 8 anyway, so we can remove these lines  
from all portfiles, right? I'm happy to do it, I just want to make  
sure this is correct before I do.
