Question: Can I somehow tell the linker to prefer "local" function calls
such that this problem is solved?
This is more of a binutils question. One way to do this reliability
with static linking is to use "ld -r --retain-symbols-file".
I can see with nm that the "--retain-symbols-file" option leads to a
library file that only exposes those symbols specified in the file
given as argument. Is that the list of symbols which also the ld tool
really sees?
Yes, if you look at "nm -D" output (or "readelf -W -s").
Why the option -r?
To produce an object which can be linked again (statically or even
dynamically, if the code is position-independent).
