With GNU ld I get:

not be used when making a shared object; recompile with

with gold build passes. GNU ld is right that GCC produce non-PIC code  
here and adding -fPIC fixes the problem.

more recent golds do not build for me with syntax errors:
In file included from ../../gold/script-c.h:211,
                  from yyscript.y:35:
../../gold/yyscript.h:195:1: error: "LENGTH" redefined

didn't looked yet into why.
