Thanks.  My problems getting it to work were:

I hadn't realized that the path to crossgcc was hard coded in xcompile, so
xcompile has to be invoked from the right spot:

for gccprefixes in `pwd`/../crossgcc/xgcc/bin/i386-elf- i386-elf- ""; do

I had expected to be able to run xcompile from the top like this:
. ./util/xcompile/xcompile > .xcompile
the way it works is:
cd util/xcompile
. ./xcompile > ../../.xcompile

The other problem I had was that the Makefile removes .xcompile on make
clean, which is not what I wanted.  I'd just generated the .xcompile file,
so I did a make clean to make sure the whole thing was compiled with the
same compiler.

I think it would be better to remove .xcompile with make distclean.  Patch
attached.
