"CPU you selected does not support x86-64 instruction set" error on Cygwin-x64

I'm trying to install openssl in cygwin by following these instructions: I dowloaded the latest tarball from this site http://www.openssl.org/source/, and put it in C:\cygwin64\home, then I run these commands from cygwin

1. tar zxvf openssl-1.0.1e.tar.gz
2. cd openssl-1.0.1e
3. ./config
4. make
5. make test

6. make install

   (Instructions from here :http://www.slideshare.net/ganaaturuu/cygwinandopen-sslinstallguide)

Up to the 3rd step ./config it works fine I believe, at least there are no errors reported, and it gives the message "Configured for Cygwin." in the end. When I run make though it gives me this output:

I searched about the "CPU you selected does not support x86-64 instruction set" and I think it has to do with CFLAGS and -march=i486 option, but I'm not at all sure as into what it should be changed.

In this How to compile a C++ program as 64-bit on 64-bit machine? question there are some solutions suggested, but in my case there are nowhere in the makefile options like -m32 and -march=i686 to remove.

If you could please show me the right direction to search this, if not the solution, I would be grateful.

I'm working on Windows 7 64-bit, with cygwin and gcc version 4.8.2.
