crossgcc: Fix buildgcc on Mac OS X

Once again, the compiler we use on Mac OS X had trouble compiling GCC.
Switch to llvm-gcc because that one works with Xcode 4.5.2 and gcc 4.7.2.
Also drop the -W flags not known to Xcode from the iasl Makefile, and
drop the --remove-destination option from the copy, because that does not
exist on Darwin.
