tools build feature sched_getcpu: Undef _GNU_SOURCE at the end

acmel · acmel · commit 44ec8396e2da · 2019-02-14T15:39:21.000-03:00
Since this feature test is included in test-all.c, the feature detection fast path compile/link phase, it can't leave any defines behind, as it can affect the tests included after it, so remove it.
