perf tools: Fix make PYTHON override
Thomas reported that make PYTHON=python2 is not work on some systems. I
can reproduce it on my ArchLinux box too.
This is because it's overridden by config/feature-checks/Makefile
regardless of PYTHON setting. I guess it's a bug slipped into during
the feature checking change.
Actually, we don't need to check python-config in the feature-checks.
We can just pass appropriate FEATURE_CHECK_*FLAGS.
