don't build libgcj dirs for Xtensa targets

[Bob Wilson]

libffi has not been ported to Xtensa targets, and apparently it is
needed to build libgcj.  This patch changes the top-level configure
script to skip libgcj for Xtensa targets.  This seems pretty standard
for embedded targets.

Tested with an xtensa-linux build of binutils and gcc and committed on
the mainlines for gcc and src.

        * configure.in: Add ${libgcj} to noconfigdirs for xtensa-*-*
targets.
        * configure: Regenerate.
