y2038: Add test coverage

It is enabled through a new rule, tests-y2038, which is built only
when the ABI supports the comapt 64-bit time_t (defined by the
header time64-compat.h, which also enables the creation of the
symbol Version for Linux).  It means the tests are not built
for ABI which already provide default 64-bit time_t.

The new rule already adds the required LFS and 64-bit time_t
compiler flags.

The current coverage is:
