  Here's the next patch in the ongoing effort to move gdbserver to the top
level.

I've edited this patch before sending to ensure it won't be too large to
be accepted by the list.  In particular, I used "git show" to create the
patch (this seems to handle moves better than "git send-email"), and I
removed the generated files.

commit 72fd760c0e9a5dbf39fce4a15bad368e525c6d7f

    Move gdbserver to top level
    
    This patch moves gdbserver to the top level.
    
    This patch is as close to a pure move as possible -- gdbserver still
    builds its own variant of gnulib and gdbsupport.  Changing this will
    be done in a separate patch.
    
    Tested by the buildbot.

Top-level configure.ac says that configs:

- or1k*-*-linux*
- score-*-*

should build gdbserver, but I don't think they have a gdbserver port (despite
them having build_gdbserver=yes prior to this patch), do they?

When autoconf-ing gdbserver, I get:

gdbserver$ autoconf
/usr/bin/m4:acinclude.m4:20: cannot open `../../config/lib-ld.m4': No such file or directory
/usr/bin/m4:acinclude.m4:21: cannot open `../../config/lib-prefix.m4': No such file or directory
/usr/bin/m4:acinclude.m4:22: cannot open `../../config/lib-link.m4': No such file or directory
autom4te: /usr/bin/m4 failed with exit status: 1

I presume these paths need to be updated?

Other than that it LGTM.  I fixed the paths above, re-generated everything, and I was able to
build fine.

Nope.  I've removed these.

Thanks, I made this change.

I think I will wait a little while longer before pushing.

This should really be done by sourcing a file in gdbserver/
If we do that, then the info about whether a system supports
gdbserver is contained under gdbserver/, and does not
require syncing with gcc whenever is changes.

See the section starting at:

  # Disable libatomic on unsupported systems.

Thanks,
Pedro Alves
