During the marina/runtime build the build could hang on OpenSolaris due to
NFS file locking problems, in the builder's home directory.

The above occurs here:
check-css-parser:

css-parser:
    [java] Java Compiler Compiler Version 4.1 (Tree Builder)
    [java] (type "jjtree" with no arguments for help)
    [java] Reading from file CSS.jjt . . .
    [java] File "Node.java" does not exist. Will create one.
<The build will hang forever at this stage, waiting to lock $HOME/.sunw/pkcs11_softtoken/objstore_info>

The workaround is to specify $SOFTTOKEN_DIR to a local file system.
See See http://opensolaris.org/jive/thread.jspa?messageID=121575

The object of this task is that we should get rid of the above dependency
the build should work and we should insulate JavaFX build from weird
problems arising from NFS/Automounter issues.
