The best way to get 32-bits is with ABI=32, that'll choose the right
asm code.  See "ABI and ISA" in the manual.

For setting the flags you can pass CFLAGS="-whatever".  In the future
we'll have -xchip=ultra2i selected automatically, but for now you need
to add it manually.

Hmm.  That file is mainly used with g++, I don't know how it ought to
go with sunpro.  Gerardo?
