linking .common and .weak definitions

[Alan Modra]

bfd/elflink.h has this to say:

     We treat a common symbol as a definition if the symbol in the
     shared library is a function, since common symbols always
     represent variables; this can cause confusion in principle, but
     any such confusion would seem to indicate an erroneous program or
     shared library.  We also permit a common symbol in a regular
     object to override a weak symbol in a shared object.

I'm curious as to why this code isn't working for you.
