Build: fix error in fixinclude configure

The stray line defining enable_darwin_at_rpath outside of the scope of
_LT_DARWIN_LINKER_FEATURES is a mistake and should be removed. It leads
to a wrong line in fixincludes/ChangeLog because there is no $1 argument
at that point.

ChangeLog:

	* libtool.m4: Fix stray call

fixincludes/ChangeLog:

	* configure: Regenerated.
