New benchmark: ULib framework

Hey,

I just added a new benchmark for ULib framework (https://github.com/stefanocasazza/ULib/tree/master).
I hope I have done things right.
installer puts `export MAKEFLAGS="-j $NUMCPUS -l $NUMCPUS"` to `~/.profile`.
But ULib seems not supporting parallel compile.
So use `make -j1` instead.
