[SDL] Cross-compiling SDL lib

[Thomas Walters]

I'm trying to cross-compile SDL for a SuperH linux platform.  
I have apparently not been successful in using the configure scripts to
cross-compile, as it always ends up compiling for the PC I'm running on.
My cross-compile environment has worked fine for kernel, X, and other apps.
I haven't been able to do all the edits by hand and get it to compile,
either though.
Any advice is apreciated.
Thanks,
