The build needs to respect $PKG_CONFIG env var like other standard build systems and the the upstream pkg-config project itself. This allows the package builder to point it to the right tool when doing a cross-compile build. Otherwise the host pkg-config tool is used which won't have access to the packages in the cross sysroot. Signed-off-by: Mike Frysinger <vapier@chromium.org>
