Comment:
The problem is that we only overwrite the symlink when cross compiling:

In regards of your issue, you don't need to cross compile i686 on a x86_64 host, just create a seperate masterdir and compile it in there.`./xbps-src -m masterdir-i686 binary-bootsrap i686` and then compile with `./xbps-src -m masterdir-i686 pkg PACKAGE`

Edit: Trying to build packages natively for a by the builders cross compiled arch or vice versa can let you run into breakage sadly quite easily. This specific issue might be one that is at least easy to fix
