Because they use defined(). The logic could be changed, I suppose, and use
?= in the appropriate places ...

The reason for this is that you can set LDSTATIC= (nothing), which makes
everything, including /bin and /sbin, _dynamic_ (by turning off the
conditional LDSTATIC?=-static in the appropriate places). So that probably
means it should have a different name from either LDSTATIC or STATIC. :)
(Yeah, I've actually built an all-dynamic system to fit on a Really Small
disk. It was a 20MB or so solid-state thingy.)

MANINSTALL=maninstall will do it for install time; however, it would still
nroff them in the tree. sigh.

Or `0' or `1'?
These can, I suppose, be set with ?= in the appropriate .mk files so that
they have a value for the various checks.
There are some other variables which would need this handling:
NOPICINSTALL (don't install _pic.a files)
NOLINKLIB (don't build .a files unless that's all that you can do, and
never install them)
