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. ] Signed-off-by: Bjørn Forsman <bjorn.forsman@gmail.com> Acked-by: "Yann E.
