Subject: [PATCH] kconfig: be more helpful if pkg-config is missing

If ncurses is installed, but at a non-default location, the previous
error message was not helpful in resolving the situation. Now, if
ncurses can't be found, and pkg-config is not installed, it will
suggest that pkg-config might need to be installed in addition to
ncurses.

I do not like to complicate the error message.

How about appending a little more info, like this?

*
* Unable to find the ncurses package.
* Install ncurses (ncurses-devel or libncurses-dev
* depending on your distribution).
*
* You may also need to install pkg-config to find the
* ncurses installed in a non-default location.
*


Thanks.

Apologies -- was a little too hasty in sending v2, and it only
included the updated message in one of the two files that needed to be
changed.
