Actually this brakes bootstrap with libgcj enabled:
make[2]: *** No rule to make target `shs.h', needed by  
`gnu/gcj/io/natSimpleSHSStream.lo'.  Stop.
make[2]: Leaving directory  
`/Volumes/UFS_Partition/pinskia/src/fsf/gcc-clean/src/objdir-nocheck/ 
powerpc-apple-darwin6.6/libjava'
make[1]: *** [install-recursive] Error 1
make[1]: Leaving directory  
`/Volumes/UFS_Partition/pinskia/src/fsf/gcc-clean/src/objdir-nocheck/

gcc_build: error: Installation failed


libgcj use -MD -MT: $(LIBTOOL) --tag=GCJ --mode=compile  
$(GCJ_WITH_FLAGS) -fclasspath= -fbootclasspath=$(here) $(JC1FLAGS) -MD  
-MT $@ -MF $(@:.lo=.d) -c

Now gcc does not produce full paths when using -MT -MD.

For an example, gnu/gcj/io/natSimpleSHSStream.d now contains:

See how limits.h does not include the full path.
