I would strongly object to any change that improves performance of the
release builds at the expense of incremental builds, e.g., by dropping
precise dependencies in order to copy more files at once. I really do
not want to go back to the world of "compatible" vs. "incompatible"

I do not really understand that... Does that mean there is something
that actively prevents make to use the builtin functions?

No, it would not. It is the current state, which does the signing at
arbitrary time, that has this inherent problem. The proposal in that
easy hack is to sign every library during linking; _nothing_ can be
using the library at that point, unless there are missing dependencies.

And I strongly suspect the next stop will be gallery creation, as gengal
is internal tool which needs a zillion libraries... If we really want to
continue to use this script for signing, IMHO it should be done as a
separate step after build.
