This isn't as complicated as you make it seem. buildworld already does 
it to build the things in lib32 and on some platforms (mips and powerpc) 
the headers are the same for both 32- and 64-bit systems and so -m32 
works perfectly already. All that is needed on x86 is some further 
header unification, which seems to be in progress. Moreover, if you are 
building standalone binaries (which the EFI stuff probably is) it should 
just work now, since standalone code doesn't depend on system headers.
