Have you considered using poudriere ?

The stage phase (the one where *-install runs) cannot remove the file
because it must be able to run again and produce the same result (make
restage), the real install phase could because it only installs the
package created earlier. The file gets created very early, in during the
extract phase, and gets removed in the clean phase.

If you never run make clean, it never gets removed.
