The following patch to src/gnu/usr.bin/egcs/common/Makfile lets me
build a libcc1.so.1.1 on mipsel.  

It still needs 
   a) Castor Fu's patch,
   b)  some more fixup to set -G0 when  producing PIC code (the default);
       that can be  lifted from the gcc config

otherwise it seems to compile its way through a kernel and egcs itself
without core-dumping.  i have no idea how correct the resulting
objects are, though.

[matt  -- does the expr.c patch help your vax quandary?]
