However, is this really a problem in practice for anything but installation directory variables? All installation directory variables are supposed to be overridable at make time, so they will all need explicit overrides (at least all the ones you are intending to substitute), and therefore they will all be fully expanded.
Regardless of what is supposed to be supported, make time overrides are not as reliable as settings from the configure script since it depends on the same overrides being applied each time that make is executed. Any variance will not be detected by make, and so already built build products won't be re-built and so they will be wrong. It is possible that make is executed several/many times during a build, and also at install time.
That is why I use configure and config.status substitutions to build the .pc file for my package. :-)
