We did some digging on IRC and discovered that this is caused by having an
old patch release (earlier than 2.7).  I've just sent a patch to check for
that instead.

[OE-core] [PATCH] GCC 7.2.0: Fix 0051-ARM-PR-82445-suppress-32-bit-aligned-ldrd-strd-peeph.patch

2017-12-05 Thread Vincent Prince 
Patch fails to apply on peep-ldrd-1.c and peep-strd-1.c.
First chunk replace ldrd by ldrd\\t then second chunk copy peep-X-1.c to 
peep-ldrd-2.c and try to replace already patched ldrd\\t
