[committed] remove 'for x in .. ${foo}' idiom from configure.in

[neroden at twcny dot rr dot com (Nathanael Nerode)]

This idiom is for Makefiles.  The shell quite happily handles
for x in ${foo}
where ${foo} evaluates to nothing. (It does nothing in this case.)

Configured and built on i686-pc-linux-gnu.  (Stage 2 bootstrap is
failing already for an unrelated reason:
../../gcc-main/gcc/gengtype.c: In function `adjust_field_tree_exp':
../../gcc-main/gcc/gengtype.c:718: internal compiler error: tree check: expected field_decl, have tree_list in gen_struct_or_union_type_die, at dwarf2out.c:11330
is the error message
)

This leaves the indentation in this file in even worse shape than before.
But I decided not to punish branch managers with a reindentation patch
right now...

	* configure.in: Remove uses of "for x in .. ${foo}" idiom.
	* configure: Regenerate.
