The normal configuration people generally test with has --prefix=/usr.

However, what this indicates to me is that the call of $(timing-type) 
needs to use $(test-via-rtld-prefix).  Does this (untested) patch help in 
your configuration using --prefix=/tmp?


Run bench-timing-type with newly built libc.

benchtests/timing-type is built with the newly built libc, so should
be run with it like actual tests and benchmarks.
