I didn't realise it's mandatory for ARMv8 when removed it. I'll back

The full regression table is:
		ILP32		LP64            AARCH32 (v4.3 & v4.3 + ILP32)

utime06         FAIL       2    PASSED	0       PASSED	0

Fortunately, there's no aarch32 regression. Note that pause01 and
setregid02 are not stable.
