Win32: i386 now assumed when crossbuilding (ticket #2416).

Previously, NGX_MACHINE was not set when crossbuilding, resulting in
NGX_ALIGNMENT=16 being used in 32-bit builds (if not explicitly set to a
correct value).  This in turn might result in memory corruption in
ngx_palloc() (as there are no usable aligned allocator on Windows, and
normal malloc() is used instead, which provides 8 byte alignment on
32-bit platforms).

To fix this, now i386 machine is set when crossbuilding, so nginx won't
assume strict alignment requirements.
