[PATCH 2.4.25] enable cross-compilation from Mac OS X

[Martin Schaffner]

Hi,

After setting up a cross-compile toolchain (using 
http://vserver.13thfloor.at/Stuff/Cross/) on Mac OS X 10.3.2, and 
applying the following patch, I was able to compile a bootable linux 
kernel with the command:
make CROSS_COMPILE=/usr/local/bin/powerpc-linux-gnu-

Please consider applying the patch to the main 2.4 tree.

I was also able to compile 2.6.1 with basically the same patch, but it 
required some additional fiddling with the makefiles in 
not-entirely-clean ways.
