Setting/overriding HOTSPOT_VERSION_STRING

[Doug Simon]

Thanks for the suggestion. However, it doesn’t seem work either:

dsimon at kurz ~/hs-comp> touch hotspot/src/share/vm/runtime/vm_version.cpp; make CONF=release HOTSPOT_VERSION_STRING=xxxxxxxx
Note: Command line contains non-control variables:
* HOTSPOT_VERSION_STRING=xxxxxxxx
Make sure it is not mistyped, and that you intend to override this variable.
'make help' will list known control variables.
