H A Dos-posix.c195588ccd55d3afa8621af3b4718babbf6cdca19 Mon Jul 13 08:36:09 CDT 2020 David CARLIER <devnexen@gmail.com> build: Check that mlockall() exists

Instead of assuming that all POSIX platforms provide mlockall(),
test for it in configure. If the host doesn't provide this platform
then os_mlock() will fail -ENOSYS, as it does already on Windows.

This is necessary for Haiku, which does not have mlockall().
