[PATCH] sparc: Prevent all but undef weak syms from becoming dynamic.

[Egeyar Bagcioglu]

Prevent sparc backend making symbols dynamic unless they are undefined
weak. By doing so, stop dynamic linker confusing these symbols with
library symbols.

bfd/ChangeLog:

2017-05-19  Egeyar Bagcioglu <egeyar.bagcioglu@oracle.com>

        * elfxx-sparc.c (allocate_dynrelocs): If a symbol isn't undefined
        weak symbol, don't make it dynamic.
