[oe] [meta-java] Building openjdk-7-jre for PPC

[Rudolf Streif]

While building openjdk-7-jre 25b30 for PPC architecture with dylan I ran
into the following issues:

The patch icedtea-jdk-nio-use-host-cc.patch is conditionally applied to PPC
only. It also requires this patch of the patch [1]. This patch has not yet
been included with meta-java although a pull request was sent a while ago.

Furthermore, the original  icedtea-jdk-nio-use-host-cc.patch includes this
change of the Sun toplevel makefile:

Index: openjdk/jdk/make/sun/Makefile

     endif
   endif
   HEADLESS_SUBDIR = headless
-  XAWT_SUBDIR     = xawt
+  XAWT_SUBDIR     =
 endif

This removes the xawt subdir from the build process resulting in XToolkit
and other Java classes not to be build and also not to be included into
rt.jar. Hence, applications using awt UI classes will break with a "class
not found" error.

I reverted the change and now it builds correctly, but I would like to
understand why this change was made in the first place.


Cheers,
Rudi
