test failures

Originally reported here:
https://bugs.gentoo.org/637488

the valgrind-3.13.0 unit tests fail on an unstable Gentoo machine. They work for me on my stable machine. Testing in a chroot, I was able to find that glibc is the source of the problem. The working machine has:
sys-libs/glibc-2.25-r9, while sys-libs/glibc-2.26-r3 is broken.

My fault for not testing git first. This was already fixed, by:
