configure: Use YEAR2038 macro when it's available.

autoconf 2.72 disabled the time size increase when LARGEFILE macro is being
used: https://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=cf09f48841b66fe76f606dd6018bb3a93242a7c9

That change can cause 32-bit Wine to return EOVERFLOW when running
stat() on a file in certain edge cases (which causes some files to
be skipped leading to applications failing to run properly).

This change was tested with both autoconf 2.71 and 2.72 to make sure
nothing broke there.
