Fix quoting of program-transform-name in toplevel configure

[Geoffrey Keating <gkeating at apple dot com>]

I wanted to do

.../configure --program-transform-name=/^[cg][^.-]*$/s/$/-3.4/

so that 'gcc' would be renamed 'gcc-3.4' but
'powerpc-apple-darwin-gcc-3.4' wouldn't be renamed.  I quickly
developed a severe case of Leaning Toothpick Syndrome.  This is a
regression from 3.3, which Just Worked.

Tested with a bootstrap on powerpc-darwin, and lots of manual
inspection of Makefiles.

	* configure.in (TOPLEVEL_CONFIGURE_ARGUMENTS): Quote properly for
	make, shell, etc.
	(baseargs): Likewise.
	* configure: Regenerate.
