Subject: [PATCH 1/4] meson: drop ln --relative check

The coreutils release that included this was in 2012. Since then,
systemd requires a newer meson, mostly uses install_symlink, and
so on. Additionally, where it does use this feature, it uses the
'-r' short flag. There are implementations of 'ln' that do have
support for '-r' but no longopts. Things will still work on those
but this check will fail.

Subject: [PATCH 2/4] meson: try BSD-style stat(1) syntax when failing mtime
 check

The system may be using a stat(1) implementation that follows
BSD-style syntax. Try that as a fallback, but do fail for real
if that also fails.

Subject: [PATCH 3/4] meson: try BSD-style date(1) for alt_time_epoch as a
 fallback

If we fail to calculate alt_time_epoch using the GNU-style syntax,
try if BSD-style syntax does not work. Fail for real if that does
not work either.
