For anyone who is interested, I managed to work it out. The result of my work is here: http://delphi.radsoft.com.au/2016/03/building-openssl-dylibs-for-ios-simulator/
There's a bunch of stuff specific to Delphi, however the script could be used for any language that can use the dylibs.

I'd like to be able to make this script build the dylibs for iOS simulator instead of the static libraries. I've attempted to modify the script to use the shared parameter in ./Configure, however that doesn't seemed to have worked, unless the dylibs are put somewhere I can't find :-)
