So upstream's sed made the assumption that there was only one argument
being passed via CC.

I've a local working fix that basically does this:

- cf_flags=`echo "$CC" | sed -e 's/^.*[ ]\(-[^ ]\)/\1/'`
+ cf_flags=`echo "$CC" | cut -f2- -d' '`

(use cut to remove the first word, assuming everything after the first word
of CC is an option).

Hongxu, would you mind if I squash this into your upgrade so we don't end
up with a revision where ncurses doesn't build?
