openssl static library for ARM

Now you can build on Raspberry Pi "out of the box". I followed your pattern with the configure script (disabling lots of features etc).

Note that the Pi is ARM v6l and the openssl target is ARMv4. However 6l is backwards compatible with 4, so I symlinked linux-armv61 to linux-armv4.

I had to modify the Makefile to link against libdl so that libcrypto.a was able to use dlopen etc. I'm not sure how you  got away with this for other architectures? If you've got a better way, let me know and I'll update the pull request.
