binutils-cross: fix '-fPIE' on mips platform
Current binutils generates problematic relocation table for executable
compiled with '-fPIE', such as dbus-daemon. That way ld.so.1 falls into
segmentation fault when accessing bad reloc entry. This pulls back one
fix from binutils CVS repo (1.267) to add PIE support back.
