hotspot: Fix dynamic link of libjvm

[Kurt Miller]

At least for gcc 3.3.5 dynamic linking of libjvm needs to use
g++ instead of LIBS_VM += -lstdc++ to avoid getting undefined
symbols. The following patch fixes it.

Tested on FreeBSD 7.0 and OpenBSD so far. A test report for
OS X would be great.

Thanks,
-Kurt
