Right the current system does not help for packages with several
executables but no library. For that we need to support convenience /
private libraries as in #276.
I do not plan to implement ad-hoc / implicit / opportunitsic sharing of .o
files. It is too hard to implement at the moment. It requires tracking
lots of information to check if the sharing is safe. It might become
possible in a future build system that obsessively tracks all
dependencies.
