Changed how?  I don't see any changes that would solve this.  With the
current trunk, running configure on GNU/Linux still produces
src/Makefile with these fragments:

    MKDEPDIR=test -d ${DEPDIR} || mkdir ${DEPDIR}
        $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<

What am I missing?

That wasn't a suggestion for a change in src/Makefile.in, just a means
to make sure Angelo's problem is due to this race, and not to
something else.
