  GDB currently doesn't build with Guile 2.2 (see PR 21104).  If one has
both Guile 2.2 and 2.0 installed, GDB will pick up Guile 2.2 first and
fail building.  Until somebody does the work of adapting the GDB code to
Guile 2.2, we should not try using it.  This patch therefore removes it
from configure.

gdb/ChangeLog:

	* configure.ac (try_guile_versions): Remove guile-2.2.
	* configure: Regenerate.

Should we perhaps have a configure-time option, by default off, to use
Guile 2.2?  Otherwise, how would that "somebody" work on fixing this
problem, if they cannot even try building with Guile 2.2?

Thanks.

They can pass --with-guile=guile-2.2.  try_guile_versions, AFAIU, 
contains the version to try by default if the version to use is not 
explicitly passed (--with-guile or --with-guile=yes).

Ah, okay.  That's good enough, I think.
