Newlib builds on i386-linux, but it is not trivial to use it because
sometimes files from the glibc installation get in the way, so I didn't
test it.  You have to build x86-linux apps with -nostdlib and manually
specify newlib's crt0.o.  Also, libgcov.a is built with glibc headers
and it expects some magic symbols that aren't in newlib.
