[PATCH v2] pkg-config default search paths

[PATCH v2] pkg-config default search paths

[Silvio Fricke]

Hi,

some cross-toolchains change the pkg-config search pathes to do some
package-config setups for cross compiling. The init of the toolchain
manipulates PKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_PATH environment variables.
A pkg-config call from kconfig searches now on the wrong place to find the
ncurses and relevant packages and gives back the wrong values for the ncurses
installation and this break the [x,g,menu]config.

Yann, please include this patch to your maintainer repository.

V2:
no changes to v1 [1], only "RFC" removed

[1] http://thread.gmane.org/gmane.linux.kbuild.devel/11993

Cheers,
Silvio

[PATCH v2] kconfig: menuconfig: pkg-config should base upon default configuration

[Silvio Fricke]

Since fc9c6e0 "menuconfig: optionally use pkg-config to detect ncurses
libs" we use pkg-config, but some cross toolchains (like yocto tc)
change the search pathes for pc files with some PKG_CONFIG_* environment
variables.

With this patch we ensure that we only get the host config options for
ncurses and don't mix with others not relevant settings.
