- From: Steve McIntyre <steve dot mcintyre at linaro dot org>

- Subject: [PATCH] ARM: Check for the FLAG_ARM_LIBHF flag in the ldconfig cache
- References: <20121203153446.GD22509@einval.com>
This will need to be applied along with the previous patch to
readelflib.c so that the output from ldconfig is kept in sync with
what ld.so expects.
