Using simply wrong hyperboles is not productive. I explained in my previous message, which you quoted below, why you cannot use a cross-compiler (such as the ppcx64 included with FPC releases on Mac OS X) to build FPC from trunk without using a special make option, and which exact make option you have to add so that it does work. Alternatively, use a cross-compiler like the one you built above. It's x86-64 binaries will be exactly the same as the ones generated by a native x86-64 compiler.

If you just need something that works, use the cross-compiler. If you want a native 64 bit build, you can create one as shown above.
