I won't explain this very well, but:

You configure+build+install once on one machine, making a binary rpm
that other people install on their machines. When they do so, they don't
run any of the Emacs Makefile pieces, the rpm just unpacks itself (like
a tar file, I guess, but smarter, registering what file gets installed
where, etc). It can choose to do various clever things at installation
time, but these things are controlled by the rpm's specification file,
not by any part of the Emacs normal installation rules.

AFAICS, there is literally nothing smart the Emacs Makefiles can do
about this issue, because they are not invoked at the relevant point.
