[boilerplate] Runtime library check

Browse source 
For the purposes of benchmarking it is useful to run cairo-perf against a
different library from the one it was compiled against. In order to do so,
we need to check that the runtime library contains the required entry
points for our targets - which we can check by using dlsym.
