If --without-wc-funcs is explicitly provided, a warning that the
option will be removed is printed.
If, instead, the check for needed wc-funcs fails, a different warning
is printed, warning that the system may no longer be able to compile
mutt starting with 2.5.0.

THIS PATCH IS UP FOR DISCUSSION. Please comment!
My thinking is that we can continue to provide the wcwidth() backup, but
the other functions being missing will trigger a configure failure
starting in 2.5.0.
