I was thinking that perhaps we could also split it into Endianness, for CHOST
voodoo, and anything else that's endianness-sensitive.

So the profiles would become;

The above is just an idea.  The main reason for splitting 'le' and 'be' is so
that the CHOST can be set correctly (mips{,64}-unknown-linux-gnu on be,
mips{,64}el-unknown-linux-gnu on le).  As for how to handle µClibc, not sure
there.  I'm guessing it'd be another profile like n32, just to s/gnu/uclibc/
in the CHOST -- certainly it will be that way whilst it's o32 only.

Anyways, those are my thoughts. :-)
