This happens if you attempt to build OpenSSL configured for 32-bit from
the Visual Studio Developer command prompt for x64. You need to use the
developer command prompt for 32 bit.

Incidentally, I would recommend against no-asm unless you really need to
use it. Using it will impact both your performance (no optimised
algorithm implementations) and your security (misses out some constant
time implementations).

Those examples are referring to OpenSSL 1.0.2 and below. The build
procedure changed significantly in OpenSSL 1.1.0.
