Subject: [PATCH][GOLD] Treat R_ARM_PREL31 as a function call in Target_arm::Scan::get_reference_flags

Hi,

    This patch fixes a number of test breakage in which R_ARM_PREL31
relocations point to weak symbols of personality routines in ARM
unwind tables.  The existing code does not general PLTs for references
from R_ARM_PREL31 and ultimately it causes tests to crash on ARM.  The
patch was tested on armv7l-linux-gnueabi in qemu.

        * arm.cc (Target_arm::Scan::get_reference_flags): Treat R_ARM_PREL31
        like function call relocations.
