As others have mentioned, hacking the front-end isn't that hard.  In  
any case though, please be aware that a precompiled binary for a non- 
MIPS target won't produce correct code if you are (for example) using  
an x86 front-end and forcing llc to generate mips code with llc - 
march=mips.  The front-end does type layout and knows very ABI things  
that have to be right for mips.
