commit b9c9ce4e598e012ca7c1813fae2f4d02395807de upstream. 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.
