different behavior with -j2 on solaris

[Peter Kurpis]

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!)
