tools build: Fixup sched_getcpu feature test
We have tools/build/feature/test-all.c to speed up feature testing, doing all tests at once, but then all tests in this file should normally pass. That is not the case with the sched-getcpu one, that wasn't passing when included from test-all.c because it needs to have _GNU_SOURCE defined before including sched.h, but _GNU_SOURCE is defined by a header included from another feature test included earlier in test-all.d, test-libpython.c, resulting in: $ cat /tmp/build/perf/feature/test-all.make.output In file included from test-all.c:121:0: test-sched_getcpu.c:1:0: error: "_GNU_SOURCE" redefined [-Werror] #define _GNU_SOURCE In file included from /usr/include/python2.7/pyconfig.h:6:0, from /usr/include/python2.7/Python.h:8, from test-libpython.c:1, from test-all.c:13: /usr/include/python2.7/pyconfig-64.h:1177:0: note: this is the location of the previous definition #define _GNU_SOURCE 1 cc1: all warnings being treated as errors Which would trigger testing the tests individually, when that _GNU_SOURCE redefinition would not take place, and the whole process would continue, just slower... Fix it.
