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. Signed-off-by: Kevin Tian <kevin.tian@intel.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

# "-fPIE" always triggers segmentation fault in ld.so.1 on mips platform,

# which was first saw on dbus-daemon. Below borrow the binutils fix from

# Its commit message says:
|

# * elfxx-mips.c (mips_elf_create_dynamic_relocation): Use section
|
||||
# sym dynindx for relocs against defined syms in PIEs.
|
||||
#
|
||||
# It's in upstream CVS now (rev 1.267), but not in current release
