tools/perf/build: Speed up auto-detection of features by adding a 'test-all' target
Concatenate all feature checks into test-all.c. This can be built and checked faster than all the individual tests. If test-all fails then we still check all the individual features, so this is a pure speedup, it should have no effects on functionality.
