It seems obvious that your tools and or compiler options  are  broken
and/or misconfigured.

Where is this "-mips2 -EL" stuff coming from? You don't find this  in

This depends on your definition of "reasonable" ;-)

Obviously this is a tool problem first. I guess you will need to  fix
this  anyway,  or  you will run into the same problems later when you
want to compile your OS kernel and/or applications.
