configure: attempt to link against tcmalloc by default if available
librbd will run up to 20% faster under small IO workloads when fio is linked against tcmalloc. By automatically linking against tcmalloc, it avoids the need to use LD_PRELOAD to pull in a faster memory management toolset. Signed-off-by: Jason Dillaman <dillaman@redhat.com>
