Hi,

this work is based on Neil's report.

I'm not sure if better would be  if the fallback O_DIRECT definition
would be removed everywhere and tests just define _GNU_SOURCE (no
library code is using O_DIRECT atm).

But the problem was found when we during some debugging use lapi/fcntl.h
inside of the library (where we don't want to set _GNU_SOURCE, otherwise
all C based LTP tests would be _GNU_SOURCE).

Kind regards,
Petr
