This patch make the OFD tests return unsupported if kernel does not
support OFD locks (it was added on 3.15).

Checked on a ia64-linux-gnu with Linux 3.14.

	* sysdeps/unix/sysv/linux/tst-ofdlocks.c: Return unsupported if
	kernel does not support OFD locks.
	* sysdeps/unix/sysv/linux/tst-ofdlocks-compat.c: Likewise.

Likewise.

This could use TEST_COMPARE (twice).

Ah right, it would have to be used to report other failures.  So your 
original patch is okay as-is.

                                                            ^

OK with parenthesis removal fix noted by Rical and Andreas.
OK since Florian's suggestion of %m is withdrawn.

OK for master.
