No and no, unfortunately.
If you looked the output of readelf -a libc.so closely, you could
find that the only text relocation occurs for __fpscr_values in
__udivsi3_i4 which is a libgcc function. So a fix would be to
write a PIC version of __udivsi3_i4. But it seems a trade-off
between slight inefficiency of the integral division and one text
relocation.
