Subject: PowerPC: Fix optimized strncat strlen call
X-Git-Tag: glibc-2.20~377
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ed36bfa18faf9be457575568e64b8409e46caa22;p=platform%2Fupstream%2Fglibc.git

PowerPC: Fix optimized strncat strlen call

This patch fixes the optimized ppc64/power7 strncat strlen call for
static build without ifunc enabled.  The strlen symbol to call in such
situation is just strlen, instead of __GI_strlen (since the __GI_
alias is just created for shared objects).
