[wwwdocs,Java] Remove five obsolete entries from java/faq.html

[Gerald Pfeifer <gerald@pfeifer.com>]

REQUEST FOR HELP:  It would be great if one of the Java experts
could advise which further entries to remove or adjust.  I volunteer
to make the actual changes, if that helps.


Now to this patch: Working on the web pages in general, I noticed a 
number of obsolete FAQ entries in our Java FAQ.  Some of them are 
(better) covered in our general documentation, some of them refer 
to really old versions of GCC.

For example, x86-64 is not included in the supported platforms 
mentioned, one entry talks about version before 3.0,...

Applied.
