>Description:
with a make rule like

foo/bar.o: foo/bar.cc
        echo CC -o $*.o $<

(and an existing foo/bar.cc
'make' ouputs 'CC -o foo/bar.o foo/bar.cc' while
'make -j2' outputs 'CC -o bar.o foo/bar.cc', ie the target misses the directory part in parallel make

>How-To-Repeat:
construct a makefile like above, create a dummy foo/bar.cc, then type 'make' or 'make -j2'

>Fix:
Other than not using directories in targets or not using -j2, none
