    make.conf.5: add CPUTYPE?= note from UPDATING
    
    Cross-compilation needs CPUTYPE to be set with ?= to be overideable via
    make targets. This has historically been mentioned in the FOOTNOTES of
    UPDATING. Note that in the CPUTYPE documentation in make.conf(5) for
    discoverability. Leave it in UPDATING for now to create no regression in
    the doc there.
