This is the wrong place to patch.
You ought to be adjusting SYMBOL_REF_LOCAL_P, by providing a modified
TARGET_BINDS_LOCAL_P.
Note in particular that I believe that you are doing the wrong thing with weak
and COMMON symbols, in that you probably ought not force a copy reloc there.
Note the complexity of default_binds_local_p_1, and the fact that all you
really want to modify is
/* If PIC, then assume that any global name can be overridden by
symbols resolved from other modules. */
else if (shlib)
local_p = false;
near the bottom of that function.
