Khem,
not sure, but this could be a problem. Unfortunately the code that
handle relocations for mips is enough different from all other
architectures.
The symbol scope redesign was mixed with another big change to handle
protected symbols, so the risk of breakage on some archs were high.
Please let me know if it helps.
Thanks,
Carmelo
