Since powerpc64 kABI does not have fcntl, the constants are adjusted with the FCNTL_ADJUST_CMD macro. The 4d0fe291aed3a476a changed the logic of generic constants LFS value are equal to the default values; which is now wrong for powerpc64. Fix the value by explicit define the previous glibc constants (powerpc64 does not need to use the 32 kABI value, but it simplifies the FCNTL_ADJUST_CMD which should be kept as compatibility). Checked on powerpc64-linux-gnu and powerpc-linux-gnu.
