maybe fix opt/5863

[Richard Henderson]

This doesn't avoid spilling the symbolic constant to memory, but does
at least put it in .data instead of .rodata.  Franz, is this enough to
get ld.so functional, or is something more invasive needed?

I've gone ahead and committed it since it's a good change either way.

        constants in .data when -fpic.
