Uh, that's what you're asking for. Specifically, you're asking it to run
make without arguments with the i386 architecture, then to run "make
--jobs=4 CC=gcc bzImage modules" with the default arch. So the makes
may be run with different architectures (which used to be disastrous:
I think kbuild can recover better now), and the first one will be run

ssh -X machine "cd /usr/src/linux && setarch i386 make --jobs=4 CC=gcc bzImage modules"
(a bit of extra paranoia there too).
btw, 'bzImage' is pretty much completely obsolete now. You should find that
ssh -X machine "cd /usr/src/linux && setarch i386 make --jobs=4 CC=gcc"
will work just as well. ('linux32' is a slightly shorter way of saying
(hm, why do you need X to build the kernel? You're not doing an xconfig
there or anything...)
