If you didn't want or need 32-bit compatibility, you could use the
nomultilib subprofiles.  These are 64-bit only.

Correct.  For backward compatibility reasons, amd64 boots in 32-bit mode. 
Actually, I believe it boots in 16-bit real-mode, but it's still handled
by the 32-bit executable format.  It switches to 64-bit mode after loading
the kernel, if a 64-bit kernel is loaded, of course.

However, with 32-bit enabled in the kernel, you should find that grub will
now execute.
