We might as well remove the test entirely as do that; it would
fail to detect "_exit" for example.
Additionally, I don't have a lot of faith in "grep -x" being
universally portable. POSIX 2018 does specify that switch, but
it mentions that it is "historically available only with fgrep".
Personally I'm okay with whitelisting pthread_exit() as
Torsten suggested.
BTW, it looks like libpq's meson.build is missing this check.
