I have a similar problem on i686-apple-darwin9:

...
	    echo "#include \"$f\""; \
	done | sed 's|../../gcc-4.4-work/gcc/||' > tmp-specs.h
/bin/sh ../../gcc-4.4-work/gcc/../move-if-change tmp-specs.h specs.h
/bin/sh ../../gcc-4.4-work/gcc/../move-if-change tmp-mlib.h multilib.h
echo timestamp > s-specs
TARGET_CPU_DEFAULT="" \
	HEADERS="auto-host.h ansidecl.h" DEFINES="USED_FOR_TARGET " \
	/bin/sh ../../gcc-4.4-work/gcc/mkconfig.sh tconfig.h
echo timestamp > s-mlib
tconfig.h is unchanged
