Can the argument to -arch be specified with an =, rather than as the next
argument, in which case this doesn't work?

Wouldn't this also do the trick, by narrowing the search to an argument
that starts with -arch, without resorting to an iteration over arguments?
case " $CC $CFLAGS $CPPFLAGS $LDFLAGS" in #(
*\ -arch*ppc* | *\ -arch*i386* | *\ -arch*x86_64*)
ac_cv_c_bigendian=universal;;
esac

Don't work too hard, make some time for fun as well!
