With automake 1.12, it's possible to use a custom test driver, and so we can use its TAP driver instead. When the sass-spec framework is set up to output TAP, then the automake driver will understand all the subtests and be able to count them individually. Note, automake 1.11 does not support custom test drivers, so I added a check in configure to see if the automake-produced Makefile.in includes the TEST_LOG_DRIVER variable. This seems to be the only way to test for the custom log driver ability. Once the automake requirements are bumped to 1.12, this test should be removed (especially if some newer automake stops defining this variable).
This requires installing a PPA to get it, but it's worth it to be able to use the TAP driver with automake. Hopefully, Travis will upgrade to the next LTS and get a newer automake within a year, anyway. Also, I disabled testing of automake-1.12+clang, since that's basically the same as automake-1.11+clang.
Only set CXX=g++ if it's not set otherwise. Normally, one would just say to do "make CXX=clang++" but Travis sets an environment variable which we need make to notice.

I didn't see this and added the Clang + gcc to the Travis matrix. You may need to rebase. |

Autoconf's TAP driver is more fully featured and is able to understand a tester (e.g., sass-spec's
sass-spec.rb) that runs multiple tests. You get a more detailed output of your test results.For example, see this Travis build (and summary) where each individual test is recognized by autoconf's make rules.
Depends on sass/sass-spec/pull/3.
