fix erroneous feature test macro check for ppoll

Browse Source 
commit f247462b08 incorrectly hid ppoll
in the presence of _GNU_SOURCE due to an oversight that defining
_BSD_SOURCE does not implicitly define _GNU_SOURCE. at present,
headers still have to explicitly check for each feature profile level;
this may be changed at some point in the future via features.h, but
has not been changed yet.
