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. :-)
