Subject: [PATCH 03/30] S390: Get rid of linknamespace failures for string
functions.
upstream-commit-id: 1d53248326dbd3c620a2bca16d35eff3019d900a
https://www.sourceware.org/ml/libc-alpha/2015-01/msg00310.html
This patch is needed to prepare for the optimized string function patchset.
This patch prefixes the ifunc-resolvers, the specific functions
and helper functions with '__' on s390-32/s390-64.
