[PATCH][COMMITTED] Fix pr 17367


This patch fixes PR 17367.

Guile 2.2 now compiles to ELF files, and I was noticing gdb complaining
when starting up.

Exception caught while booting Guile.
Error in function "load-thunk-from-memory":
not an ELF file
./gdb: warning: Could not complete Guile gdb module initialization from:

I traced this to the wrong guild program being used.
guild should come from the specified guile distribution,
but /bin/guild was being used instead (which is guile 2.0).

Regression tested on amd64-linux with guile 2.0.11 and guile trunk.

	PR guile/17367
	* acinclude.m4 (GDB_GUILE_PROGRAM_NAMES): Pass guile version as
	last parameter to pkg-config, not first.
	* Pass --with-guile provided pkg-config path to
	* configure: Regenerate.
