BUILD: initcall: mark the __start_i_* symbols as weak, not global

Browse Source 
Just like for previous fix, these symbols are marked ".globl" during
their declaration, but their later mention uses __attribute__((weak)),
so it's better to only use ".weak" during the declaration so that the
symbol's class does not change.

No need to backport this unless someone reports build issues.
