[ELF] --fortran-common: prefer STB_WEAK to COMMON

Authored by MaskRay on Jul 13 2021, 3:29 PM.



The ELF specification says "The link editor honors the common definition and
ignores the weak ones." GNU ld and our Symbol::compare follow this, but the
--fortran-common code (D86142) made a mistake on the precedence.

LGTM. I don't think that the original intention of D86142 was to differ in this regard. Will be worth giving sfertile some time to object if there is a specific reason.
