Add an LWP version of the hcrypto library
hcrypto uses a single pthread mutex, which is only required when
we're running in a pthreaded world (in a cooperative threading world
such as LWP, there's no way that two processes can both access the
Fortuna PRNG at the same time)
So, build an LWP version of hcrypto which just disables the mutexes.
