[svn-r11566] Purpose:
Makefile bug fix

Description:
Previously, automake didn't output rules to build perform/mpi-perf or
the test/gen_* programs.
Now these can be built by typing 'make mpi-perf' (or 'make foo') or by
configuring with --enable-build-all.

Solution:
Automake doesn't like having rules for programs it doesn't build.  Tricked
it by having these programs built "sometimes"--whenever the user enables
--build-all.  This should be used mostly for testing and to ensure that
these helper programs compile.

***IMPORTANT***
These programs do *not* currently compile.  When --enable-build-all is used
(not the default), gen_new_fill fails because it uses an old API.  This is
an existing "bug" that has simply been exposed by this checkin.

Platforms tested:
sleipnir, modi4, sol
