[PATCH] Unbreak program transformation name `configure' options

["Maciej W. Rozycki" <macro@codesourcery.com>]

Hi,

 This commit:

2012-04-19  Pedro Alves  <palves@redhat.com>

	gdb/
	* configure.ac: Remove gl_EARLY, gl_INIT and AM_INIT_AUTOMAKE
	calls.  Configure gnulib using ACX_CONFIGURE_DIR.

removed the handling of the program transformation name `configure' 
options in this subdirectory (that was pulled implicitly with 
AM_INIT_AUTOMAKE).

 OK to check in the following fix that reinstates it?

2012-04-26  Maciej W. Rozycki  <macro@codesourcery.com>

	gdb/
	* configure.ac: Add AC_ARG_PROGRAM.
	* configure: Regenerate.

  Maciej
