split check target into check and test targets

[Daily, Jeff A]

I attempted to split the "make check" target into "make check" (build 
check_PROGRAMS) and "make test" (run check_PROGRAMS).  However, I get warnings 
that check-am was overridden.  How might I split the building and running of 
check_PROGRAMS and still use the generated parallel-tests using TESTS?  Thanks.
