Should it be marked with __attribute__((weak))?

...
weak
 The weak attribute causes the declaration to be emitted as a
 weak symbol rather than a global. This is primarily useful in
 defining library functions which can be overridden in user code,
 though it can also be used with non-function declarations. Weak
 symbols are supported for ELF targets, and also for a.out
 targets when using the GNU assembler and linker.
