[RFA] gdbserver 1/3 - top level config

- Subject: [RFA] gdbserver 1/3 - top level config
This is the first of three interdependent patches to revamp gdbserver.
This first patch:
- always builds gdbserver if it is configured
- configures gdbserver only for Linux/{ARM,ia64,i386,m68k,mips,ppc,sh}.
Those seven targets will hereafter be referred to as "The Seven",
since I'm really tired of typing that list over and over :)
This disables all the non-Linux targets, which I'm reasonably certain
do not work. At least the NetBSD targets should be very easily
reconstitutable. It also disables s390 and x86-64. That's just
because I didn't have the necessary information handy for either, or a
way to test either. I'll try to get those two fixed soon, as well as
Sparc/Sparc64 which did not work at all.
Actually, reading over this list, I believe that SH support is actually
being contributed by this patch. I did it six or eight months ago, but
in this new framework, so it couldn't be contributed before this.
This patch contains only changes to top-level configury. OK to commit?

* configure.tgt: Configure gdbserver only for known working
targets. Set ${build_gdbserver} instead of modifying ${configdirs}.
* configure.in: Check ${build_gdbserver}. Put gdbserver/ into
SUBDIRS if it is configured.
* configure: Regenerated.
