That error means you are trying to link against i386 libraries with -m64 
... which you can't do. You need to remove all i[3,4,5,6]86 RPMS from an 
x86_64 build server except for glibc.i686 and glibc-devel.i386 (and 
those packages are only needed to build a couple packages).

First thing is that building on x86_64 is quite a PITA.

You will need to either use mock with the appropriate configuration file 
   or you will need to create a build machine that has only x86_64 RPMS 
(otherwise you will either try (and fail) to link to i386 libraries ... 
or if you have enough i386 software actually installed (binutils, 
libgcc, glibc and glibc-devel) then you will actually link against i386 
libraries).

This will most likely make your binaries not work, or require mixed 
software on other installs.

So, I would recommend that you create a build VM or use mock.

Thanks,
