True, but I believe those packages should either be fixed, or marked
as depends on !BR2_PREFER_STATIC_LIB. As we have discussed a number of
times in the past, I believe that a "prefer static libraries" option
doesn't make much sense. Either you /want/ static libraries, or
you /don't/ want static libraries. But a "prefer" option that doesn't
even tell you for which libraries static linking or dynamic linking
will be used is kinda useless. And since kconfig doesn't allow us to
easily provide per-package options to allow the user to define on a
per-library basis whether it should be built static or dynamic, I
believe the only two selections that make sense are: full dynamic or
full static.

Or, as we discussed when talking about building with -fPIC: build
static /and/ dynamic, build dynamic only (default), build static only.

Indeed. I must say I'm somewhat surprised that something relatively
simple like kmod doesn't support static linking.
