adding --openssldir="/prefix" makes no difference to the install paths, 
nor would I expect it too after a peruse of the configure.

I found using "--cross-compile-prefix=x86_64-w64-mingw32-" instead of 
presetting CC etc as I did led to an error:-

../x86_64-w64-mingw32/bin/as: unrecognized option '--noexecstack'


which is odd as I preset AS to x86_64-w64-mingw32-as, and I presume that 
the ../x86_64-w64-mingw32/bin/* binaries are the same as the prefixed ones..

I know you do and very useful they are too. However I'm just trying to 
roll my own now so I can include other things :P
