If you touch Makefile.in and then do make -j2 cc1, make goes into an infinite
loop for me (3.81).

It hangs at

...
/bin/sh /space/rguenther/src/svn/trunk/gcc/../move-if-change
tmp-mlib.h multilib.h
echo timestamp > s-mlib

while make cc1 (without -j2) continues with

echo timestamp > s-mlib
lsf="/space/rguenther/src/svn/trunk/gcc/cp/lang-specs.h
/space/rguenther/src/svn/trunk/gcc/fortran/lang-specs.h"; for f in
$lsf; do \
            echo "#include \"$f\""; \
        done | sed 's|/space/rguenther/src/svn/trunk/gcc/||' > tmp-specs.h
/bin/sh /space/rguenther/src/svn/trunk/gcc/../move-if-change tmp-specs.h specs.h
echo timestamp > s-specs
