[Bug ld/9687] Weak symbols not working on mingw32

mingw32 does not support weak definitions, only "weak externals"   As documented
in ld.info:

_weak externals_
     The Windows object format, PE, specifies a form of weak symbols
     called weak externals.  When a weak symbol is linked and the
     symbol is not defined, the weak symbol becomes an alias for some
     other symbol.  There are three variants of weak externals:
        * Definition is searched for in objects and libraries,
          historically called lazy externals.

        * Definition is searched for only in other objects, not in
          libraries.  This form is not presently implemented.

        * No search; the symbol is an alias.  This form is not presently
          implemented.
     As a GNU extension, weak symbols that do not specify an alternate
     symbol are supported.  If the symbol is undefined when linking,
     the symbol uses a default value.
