Third-party descriptions: be flexible on PKG_CONFIG_PATH

Using only our third-party descriptions, the build is independent of
PKG_CONFIG_PATH. However, when combinging our third-party descriptions
with dependencies taken from the system via pkg-config there is a
dependency of PKG_CONFIG_PATH due to those indirect dependencies.
Therefore, allow flexible PKG_CONFIG_PATH to support such a mixed
bootstrapping.
