With all things being equal, -j2 causes an apparent failure of
the $(wildcard ...) function for us. Specifically, it does not
expand to a file (util.o in the example below) thus showing
the failure mode when
(.) -j2 is used at the top of the build tree
and does expand (i.e. to util.o) showing expected behavior when
(1) -j2 is not used
(2) -j2 is used in a make call in the subdirectory (as
contrasted with the top of the build tree)
Some cut-and-pasted details follow.
(Note: I could not locate the bug report archive and would appreciate
knowing where it is, so I am not being redundant. Also, I would
appreciate an ack on this email. Thanks!)
