Probably. Unfortunately with kconfig, we cannot easily add one option
for debug symbols, static/dynamic linking to each package. It would add
gazillions of options.

One possibility would be to have one global string option that you
could fill in with a space-separated list of packages that you want to
be built statically, even if the rest of the system is built
dynamically.

Best regards,

Thomas
