[Buildroot] [PATCH resend] 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.
