Re: Fix in-src-tree builds by making gdbserver/gnulib/ a separate library (a la libiberty, etc.), and adding ACX_CONFIGURE_DIR.

gdbserver is a target program, so if one wanted a "one tree" build,
one would need to configure gnulib for both host and target (when host
!= target).

If there's no disagreement that moving gdbserver to the top level is
the right thing to do (I think it is) then I think time spent doing
something different is ultimately time not well used.

If gcc can move libgcc to the top level, we should be able to move gdbserver.
