When I first looked at it last week, I came to the conclusion that MIPS
support in EGCS for Linux was a hoax.  You could probably graft this
patch into 1.1.1 pretty easily:

	http://www.cygnus.com/ml/egcs-patches/1998-Dec/0052.html

You will probably also need to patch that patch with a patch like this
untested one making its debut on egcs-patches right now:

* configure.in: Support mips-linux in either endianness.

And things like this support my hoax theory...

With the first patch, EGCS snapshots would bootstrap on the target mentioned
in the above URL.

Enjoy.
