Subject: [PATCH] kconfig/lxdialog: get ncurses CFLAGS with pkg-config

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

This makes "make menuconfig" also work on systems where ncurses is not

installed in a standard location (such as on NixOS).

This patch changes ccflags() so that it tries pkg-config first, and only

if pkg-config fails does it go back to the fallback/manual checks. This

is the same algorithm that ldflags() already uses.

[This patch is already applied upstream (is part of linux v3.18):

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=be8af2d54a66911693eddc556e4f7a866670082b

I'm adding this instead of doing a full upstream kconfig sync because

there was a conflict in one of the Buildroot kconfig patches (against

linux 3.18-rc1), which I was unable to resolve. Just drop this patch next time

Buildroot kconfig is synced against upstream.
