Globally disable PKG_CONFIG_PATH
If PKG_CONFIG_PATH is set in the environment, it allows pkg-config to look for libraries outside of the buildroot tree. This is a problem both for host and target builds. To avoid it, globally set an empty PKG_CONFIG_PATH in the environment. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
