If you notice, the 2 links created on jdk7-bin are unnecessary.  The
plugins have already been linked to the jdk$VER directory, so there's
no dependency on the created links.

So that's a way to solve the soft links issues.  As I tested with old
icedtea7, I didn't realize it.

Something I supposed though, which is not necessarily true, is that no
matter the JAVA provider, we would have JAVA_HOME set for it, and the
binary providers don't include a java.sh for profiles.d, so at least
it has to be set by hand before, if not provided by its spell, with
the spell I provided...

One alternative is to evaluate JAVA_HOME, and if not present, then go
look for the presence of the directories that could provide it, to set
JAVA_HOME with it, and if none present, then kill the cast, and
suggest to cast JAVA7.  Notice some path should be found if JAVA7 is
installed, :-).

Supposing a dependency on JAVA7 only, and that jdk7-bin gets fixed not
to create the unnecessary soft links, then it's a matter of adding the
JAVA_HOME evaluations to BUILD, before setting OPTS...
