Looks good, and thanks for fixing this quickly!.

With the removal of the -d64 flag, bootcycle builds started failing.
This patch stops trying to use -d64 completely for the boot jdk since
it shouldn't be needed for either JDK 8 or 9. The checks that used
this parameter to see if the JVM was 64 bit has been rewritten to
instead look at the version string.
This is for JDK 10.
