I have removed 32-bit bits as much as I could easily. So I do not
care if any such setting is enabled or missing.
I had not touched any other *elf64* settings ( besides *.aslr.enable
& *.aslr_pie.enable).

You should have sent your question directly to -questions@ list instead
of privately asking me.

After successful "build" (as in "make build") of the port, remove it ("make
deinstall") & then install it ("make install") ...
# make build && make deinstall && make install
... or, wait for "make install" to fail as the port had already been
installed. Then you could remove it either via pkg-delete(8) or via
"deinstall" make(1) target; run the "install" target again.
