Thanks Dan, but a few questions...
>>From looking at the code, it seems that the ABI and ISA are orthagonal. So
would it not make more sense to have two different features "sgi-abi" and
"sgi-isa". Or is there a reason why you picked the single one instead?
Also choosing the ABI-ISA looks similar to the problem of cross-compilation,
that is telling the single local compiler what "platform" to compile for.
Would it then be preferable to better support cross-compilation instead of
adding more platform specific features? For example we could add an
"architecture" feature, this would map directly to your "sgi-abi-isa"
