Unless you consider that nothing will ever move (be that a single file
or a whole folder) using this is strongly ill-advised.
One *might* be able to get around it by following the approach use by
xserver (configure keeps track of the static libraries used for the
final foo.so binary) although reportedly that did break something in
their dependency tracking.

Thank you for that. Pretty sure others are abound to run (have ran)
into similar issues.
