usr.bin/make 2nd try: we are POSIX

[Max Okumoto <okumoto@xxxxxxxx>]

Remove ifdef since the code has always been built with POSIX defined.

Author: harti
Log:
Eliminate the define for POSIX and build with Posix behaviour.
Our make has been build with POSIX enabled from the first day
and the ifdef'ed out code served no purpose.
