This should be fixed in trunk by this patch in April.

        * arm.cc (Arm_output_section::Arm_output_section): Set SHF_LINK_ORDER
        flag of a SHT_ARM_EXIDX section.
        * testsuite/Makefile.am (arm_exidx_test): New test rules.
        * testsuite/Makefile.in: Regenerate.
        * testsuite/arm_exidx_test.s: New file.
        * testsuite/arm_exidx_test.sh: Same.

2.21 is still broken.  This probably is not a big issue.  The problem was that
gold incorrectly missed setting SHF_LINK_ORDER in .ARM.exidx section headers. 
I am not aware of any use of that flag in unwinding.
