        * gdbserver/configure.srv: New file.
        * gdbserver/configure.in: Use configure.srv instead
        of the host/target makefile fragments.  Set GDBSERVER_DEPFILES
        from it.
        * gdbserver/configure: Regenerated.
        * gdbserver/terminal.h: New file.
        * gdbserver/Makefile.in: Update for configure changes.  Remove
        more unneeded include paths.
