Adding javac flag -XDallowInterceptTypes for javadoc

[Henry Jen]

Hi,

I am trying to build TL repo which support intercept type cast, in order
to make the build, I added

OTHER_JAVACFLAGS += -XDallowIntersectionTypes

to make/java/jave/Makefiles, which works for new build, but failed for
old build in javadoc step.

Would you please advise what would be the right approach to fix this for
javadoc?

Cheers,
Henry
