 This bug affects bfd ld on ARMv7, causing ld to incorrectly emit
 R_REL_COPY relocations, breaking tables-next-to-code. We've known about
 it for several years now and there is not yet a fix upstream. Previously
 we would simply force use of ld.gold on ARM. However, given the rework
 of linking configuration, I thought a more principled solution was in
 order.

 Test Plan: Validate on armv7
