Support building with PNaCl.
PNaCl needs OPENSSL_NO_ASM to work and a couple of cases were missing
because it hasn't previously been tested.
Additionally, it defined _BSD_SOURCE and others on the command line,
causing duplicate definition errors when defined in source code.
It's missing readdir_r.
It uses newlib, which appears to use u_short in socket.h without ever
defining it.
