BUILD: add an AIX 5.2 (and later) target.

It's always a real pain to build on AIX and I constantly lose my flags,
so let's store them once for all in the Makefile.

 AIX 5.3 is known to work with the generic target. However, for the binary to
 also run on 5.2 or earlier, you need to build with DEFINE="-D_MSGQSUPPORT",
 otherwise __fd_select() will be used while not being present in the libc.
