[drlvm] java.vm.version

[Mark Hindess]

DRLVM current reports the java.vm.version system property as "11.2.0".
It has done so since at least 2006-11-30.  I think it would be more
constructive if this version string changed over time.

I propose changing this to be constructed from the existing variables
defined vm/vmcore/include/version_svn_tag.h, namely:

  JAVA_RUNTIME_VERSION "r" VERSION_SVN_TAG

which will be:

  1.5.0r921154
  1.6.0r921154

for the trunk and java6 build respectively.

Does this seem reasonable?

Regards,
 Mark.
