Sanity check please: minor hack to mktest.pl

I've a suspicion that the test failures I have been seeing on Solaris are 
because 'make test' is being run with parallel make instead of serial make. 
  I don't want to switch entirely to serial make because the builds already 
take a long time.  I've therefore hacked mktest.pl to use /usr/ccs/bin/make 
for the 'make _test' step only - can someone confirm that I haven't missed 
any other places that need changing?

Thanks,
