[perf] Force rebuild if make fails

Browse source 
The build system has a singular failure whereby if a backend disappears
between on compile and the next, automake will fail to reconstruct the
Makefiles - resulting in a broken build. Attempt to fix this by removing
the build dir and recloning, which should work for any corrupt caches but
obviously will fail again at a true build failure.
