Acked-by: Thomas Petazzoni <thomas.petazzoni at free-electrons.com>

but a followup patch might be useful:

I think the PKG_CONFIG variable can be removed as well. All packages
are being compiled with TARGET_MAKE_ENV, which includes
PATH=$(TARGET_PATH), which ensures that $(HOST_DIR)/usr/bin is in the
PATH before all other directories in your PATH. So 'iw' should
automatically pick up the right pkg-config without having to specify
this PKG_CONFIG variable.

Best regards,

Thomas
