commit 947388eb043ea1c44b37df94046e1eee790ad776

Intercept strncmp for glibc ld.so v2.28+
In glibc 5aad5f617892e75d91d4c8fb7594ff35b610c042 (first released in
v2.28) a call to strncmp was added to dl-load.c:is_dst. This causes
valgrind to complain about glibc's highly-optimised strncmp performing
sixteen-byte reads on short strings in ld.so. Let's intercept strncmp in
ld.so too so we use valgrind's simple version to avoid this problem.

Subject: [PATCH] Bug 454040 - Add intercept for memmem on s390x
Since memcheck may report false positives in an optimized version of memmem on
s390x, add an intercept for memmem on s390x platforms.
