Sam Lunt b9c9ce4e59 perf tools: Support Python 3.8+ in Makefile 
Python 3.8 changed the output of 'python-config --ldflags' to no longer
include the '-lpythonX.Y' flag (this apparently fixed an issue loading
modules with a statically linked Python executable).  The libpython
feature check in linux/build/feature fails if the Python library is not
included in FEATURE_CHECK_LDFLAGS-libpython variable.

This adds a check in the Makefile to determine if PYTHON_CONFIG accepts
the '--embed' flag and passes that flag alongside '--ldflags' if so.

tools/perf is the only place the libpython feature check is used.
