Now that libsupport abstract Linux possible missing support (either due FS limitation that can't handle 64 bit timestamp or architectures that do not handle values larger than unsigned 32 bit values) the tests can be turned generic. Checked on x86_64-linux-gnu and i686-linux-gnu. I also built the tests for i686-gnu. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
