They do. But they will not be linked because of priority.
So I have program.c with:
void "weak" foo() {};

and target.c:
void foo() {do_something();}

If I link them together into static library and link with ELF file then
"weak" foo() is going to be executed.

The only one way to workaround it is link program.c.o and target.c.o as
object to ELF file.
