openssl compilation flags are wrong

[Sean McNeil]

Hi,

Just trying to recompile openssl on my -CURRENT amd64 machine and I see
that a flag is passed improperly:

cc: -lpthread: linker input file unused because linking not done
cc: -rpath: linker input file unused because linking not done
cc: /usr/local/lib: linker input file unused because linking not done

This happens for all files as -lpthread is passed instead of -pthread.

Cheers,
Sean
