Don't invoke pkg-config unnecessarily.

Browse source 
Previously, we always invoked AX_PKG_CONFIG_CHECK() for a disabled component (i.e. a component which we provide but which was disabled on the configure command line).  This is both excessive (because we only need to run this check for components that will be needed during the build) and insufficient (because we also need to run it for components from other Cryb projects).
