Hello Volker,
The change looks good, but now that we no longer link against
libawt_headless, we should also remove the make dependency a few lines
down. (Should have been done already for Solaris.)

Hi,
can I please have a review for this tiny AIX cleanup:
http://cr.openjdk.java.net/~simonis/webrevs/2018/8201524/
https://bugs.openjdk.java.net/browse/JDK-8201524
This is a follow up change of JDK-8196516 which discovered that on AIX
libfontmanager is always linked against libawt_headless at build time.
If we are running in a headfull environment, libfontmanager will
dynamically load libawt_xawt which is not good because libawt_headless
and libawt_xawt define some common symbols. If we're running in a
headless environment, libawt_headless may be loaded a second time (at
least on Linux/Solaris) which isn't good either.
Both of these scenarios haven't caused any problems on AIX yet, but I
think it's good to cleanup the AIX implementation as well and don't
link libfontmanager against libawt_headless anymore. In order to
achieve this, we have to allow unresolved symbols during the linking
of libfontmanager. This can be easily achieved by adding the additions
linker flag "-Wl$(COMMA)-berok" through LDFLAGS_aix. This works fine
for AIX because options which come later on the command line take
precedence
over earlier ones.
Thank you and best regards,
Volker
