Patch: allow specifiying flags to the VM used in javac script

[Robert Schuster]

Hi,
great stuff I forgot the actual patch. :)

@Twisti/Martin: The patch only affects the 'javac' script in IcedTea's
toplevel directory. This script calls ecj directly IOW without calling
another ecj program/script.

Regards
Robert
