    includes/Stg.h: define _DEFAULT_SOURCE for glibc-2.20
    
    _BSD_SOURCE we are using for 'gamma()' and friends
    was deprecated in glibc-2.20 in favour of '_DEFAULT_SOURCE'.
    
    gcc says:
    
        In file included from /usr/include/math.h:26:0:
            0,
                             from includes/Stg.h:69,
                             from /tmp/ghc19488_0/ghc19488_2.hc:3:
    
        /usr/include/features.h:148:3:
             warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
             # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
               ^
    
    Patch fixes testsuite failures on UNREG
    (stderr are not cluttered by warnings anymore).
