From c0f975af1745391749e4306aa8081b9a4d2cced8 Mon Sep 17 00:00:00 2001 From: John Millikin Date: Wed, 23 Dec 2020 14:04:23 +0900 Subject: kconfig: Support building mconf with vendor sysroot ncurses Changes the final fallback path in the ncurses locator for mconf to support host compilers with a non-default sysroot. This is similar to the hardcoded search for ncurses under '/usr/include', but can support compilers that keep their default header and library directories elsewhere. For nconfig, do nothing because the only vendor compiler I'm aware of with this layout (Apple Clang) ships an ncurses version that's too old for nconfig anyway.
