RFR(S): 8155236: AIX: fix detection of Xrender extension

[Volker Simonis]

Hi Tony,

the OpenJDK build currently only depends on original IBM AIX packages
or packages from the "AIX Toolbox for Linux Applications"
(http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/download.html)

These basically are:

freetype2-2.3.9-1.aix5.2.ppc.rpm
freetype2-devel-2.3.9-1.aix5.2.ppc.rpm
fontconfig-2.4.2-1.aix5.2.ppc.rpm
zlib-devel-1.2.3-4.aix5.2.ppc.rpm
pkg-config-0.19-6.aix5.2.ppc.rpm

http://hg.openjdk.java.net/ppc-aix-port/jdk7u/raw-file/tip/README-ppc.html
contains some outdated build instructions for OpenJDK 7 on AIX, but
the dependencies should be still the same.

Notice that OpenJDK currently only builds with XLC on AIX.

Regards,
Volker
