From 120010cb1eea151d38a3e66f5ffc79a0c3110292 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 2 Mar 2017 12:55:49 -0300 Subject: tools build: Add test for sched_getcpu() Instead of trying to go on adding more ifdef conditions, do a feature test and define HAVE_SCHED_GETCPU_SUPPORT instead, then use it to provide the prototype. No need to change the stub, as it is already a __weak symbol.
