    Use --disable-gdbserver in build-many-glibcs.py.
    
    Now that binutils-gdb has gdbserver at top level, an extra
    --disable-gdbserver configure option is needed when configuring
    binutils from a git checkout to avoid it also building gdbserver
    unnecessarily (although fairly harmlessly).  This patch updates the
    options used in build-many-glibcs.py accordingly (although this might
    end up not being needed depending on what happens regarding whether
    gdbserver gets built for host != target).
    
    Tested with a build-many-glibcs.py compilers build for
    aarch64-linux-gnu using binutils-gdb master.
