Omair already pointed you to a number of threads discussing this aspect 
so I won't go into it further.

The --with-extra-*flags are only used by hotspot and JDK. They are 
primarily intended to pass through compiler flags when doing 
cross-compilation. They are not intended as a general mechanism for 
passing additional flags - most of which is internalized in the 
makefiles (either directly for hotspot, or via what configure sets up).

That would be me I guess. :) The cross-compilation support was defined 
based on our own internal needs for doing ARM and PPC builds, and how we 
previously achieved that. It is far from general purpose. There is 
already some description of it in the README-builds.html.
