The definition of O_DIRECT in src/trunc.c causes xfstest 125 to fail
when run on a Pandaboard. On ARM, the value used (0x040000) is
O_DIRECTORY rather than O_DIRECT as it is on x86. Prefer the platform's
native definition of O_DIRECT supplied by fcntl.h if available. Also,
fix a couple of error messages to properly reflect their context.
