This should pick up our optimised memchr(), strlen(), and strlcpy() when strlcat() is called. Tested by: developers@, exp-run Approved by: mjg MFC after: 1 month MFC to: stable/14 PR: 275785 Differential Revision: https://reviews.freebsd.org/D42863 (cherry picked from commit 2b7b03b7ae179db465c1ef19a5007f729874916a)
