Why that in a release?

Besides this, you can override any variable defined in config.mk
using make in this way:

make <var1>=<value> <var2>=<value>

So I really see no need for using the ?= operator (dunno how
porspacele it is btw. The Makefile's work out of the box
with GNU and MacOS™ make and are still quite readable
(compared to that stupid junk called automake).
