The symbols in question - there are actually two - are indeed present
in glibc, but recent releases have given them a version of GLIBC_PRIVATE
to indicate that they are for internal use only. The symbols in question
are:

  __pthread_clock_gettime
  __pthread_clock_settime
 
Both of these are referenced in valgrind's special libpthread.so and
hence are picked up by rpmbuild as dependencies. The problem is that
rpm knows that those are private symbols and doesn't consider that
the glibc package satisfies them, hence the error.

You can force the install with --no-deps and it will all run just
fine, or you can hack the package building to avoid adding that
dependency, which is what I do. I have this script in my RPM sources
directory as valgrind-find-requires:

#!/bin/sh

/usr/lib/rpm/find-requires "$@" | grep -v GLIBC_PRIVATE

and then I add this macro to my valgrind.spec file:

%define __find_requires %{_sourcedir}/valgrind-find-requires
