lua bindings test (framework?) failure about flux-core HOT 2 CLOSED

This issue appears to be because newer automake on ubuntu 14.04 has switched to parallel-tests by default:

https://www.gnu.org/software/automake/manual/html_node/Parallel-Test-Harness.html

The parallel test driver in automake requires a different set up (AM_TESTS_ENVIRONMENT instead of TESTS_ENVIRONMENT, use of TEST_EXTENSIONS and XX_LOG_COMPILER, etc) than the simpler serial tests driver, so this was breaking the lua tests (tests in TESTS are executed directly instead of under lunit or something)

We can fix this in two ways

1. Update the definitions in src/bindings/lua/Makefile.am to work with parallel-tests
2. Add serial-tests to automake options to force the same behavior between older automake and newer automake.

Though the parallel-tests is the preferred method for newer automake, I lean toward option 2 above just so that there is consistent behavior between development environments. The big problem there is that the serial-tests option is not going to be recognized by older automakes, so there will be a warning like

configure.ac:15: option `serial-tests' not recognized

I will have to see if there is a different way around this. I guess for now fixing up the lua tests to run in the parallel-tests environment is our only good solution...

Ugh. Number 1 above doesn't work because the older TESTS_ENVIRONMENT variable seems to still mess up the newer automake's parallel-tests.

So far, there doesn't seem to be a good solution... except maybe creating a wrapper script for the lua tests that can be added to TESTS. configure.ac and Makefile.am's just weren't really meant to support multiple versions simultaneously...
