moving GDB_TK setting into configure.in [FIXME]

[Phil Edwards <pedwards at disaster dot jaj dot com>]

The toplevel configure has some 'FIXME' notes about code that should
be moved from configure to configure.in.  This patch would do that.
The DJGPP-related bits have already been tested and approved (a few months
ago by Eli), but I wanted to hear a yes/no on the GDB_TK part.

I tried this back in January, but got bogged down in more important things.
The 'FIXME's keep nagging at me, though.  :-)
