[PATCH] icedtea6: split outputs

[Ricardo Wurmus]

Hi Guix,

when I originally packaged up OpenJDK with IcedTea it did not occur to
me that the build output in openjdk.build contained multiple
distributions of the JDK and JRE in addition to various binaries and
libraries.

What really matters are these distribution directories named
"j2re-image", "j2sdk-image", and "j2sdk-server-image".  They contain the
JRE, the JDK with examples, and the JDK without examples, respectively.
The binaries and libraries contained in these directories are duplicates
of those in the various directories of "openjdk.build".  The
"j2sdk-server-image" is virtually identical to the "j2sdk-image", but it
lacks examples, so I chose to use the latter as the JDK.

The first attached patch splits the outputs of the icedtea6 package into
"doc", "jdk", and "out", containing the documentation, the contents of
the "j2sdk-image" directory, and the contents of the "j2re-image"
directory, respectively.

The other two patches update the packages for Ant and R, such that they
depend on the "jdk" output.

~~ Ricardo
