share/mk/: Use ifndef and := instead of ?=

The semantics of '?=' are similar to those of '=', but we need simple
assignment as if ':=', so we can't use '?='.  In the future, we'll be
able to use '?:='.  For now, let's use ifndef.

Fixes: 0d69e51cd4b8 (2025-02-10; "share/mk/: Use ?= assignments for user-facing variables")
