From: He Zhe <zhe.he@windriver.com>
Since Python v3.8.0, with the following commit
0a8e57248b91 ("bpo-36721: Add --embed option to python-config (GH-13500)"),
--embed option must be passed to "python3-config --ldflags --embed" or
"python3-config --libs --embed" to get "-lpython3.8".
To make it compatible with all Python versons, according to the suggestion
in the commit log, we try with --embed first and then witout it if fails.

Yes, it is due to that the command before "||" prints some usage on failure and thus messes up the whole string. And I've tested Sam's patch. It works. BTW, my [2/2] may still make sense.

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.
