    tools build: Fixup sched_getcpu feature test · 1e6e7eae
    Arnaldo Carvalho de Melo authored
    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.
