Most of the pc98 replication these days is in the form of "#include
<i386/foo.h>" and we install i386/include into /usr/include/i386 as
well as pc98/include into /usr/include/machine.

I'm working in a similar vein.  For a while, one has had to specify
TARGET_BIG_ENDIAN in order to build big endian MIPS or ARM binaries.
This is lame.  I've eliminated it and have made it possible to build
mipsel, mipseb, arm or armeb binaries by setting TARGET_ARCH to one of
these, while still sharing all the mips code in one directory and all
the arm code in another.
