MINOR: build: add aix72-gcc build TARGET and power{8,9} CPUs
As haproxy wont build on AIX 7.2 using the old "aix52" TARGET a new
TARGET was introduced which adds two special CFLAGS to prevent the
loading of AIXs xmem.h and var.h. This is done by defining the
corresponding include-guards _H_XMEM and _H_VAR. Without excluding
those headers-files the build fails because of redefinition errors:

Futhermore, to enable multithreading via USE_THREAD, the atomic
library was added to the LDFLAGS. Finally, two new CPUs were added
to simplify the usage of power8 and power9 optimizations.
This TARGET was only tested on GCC 8.3 and may or may not work on
IBM's native C-compiler (XLC).
Should be backported to 2.1.

You can easily define your own target with the GNU Makefile. Unknown targets
are processed with no default option except USE_POLL=default. So you can very
well use that property to define your own set of options. USE_POLL can even be
