Currently the default is for a multilib profile. If the user does not enable IA32 Emulation support in their kernel under Executable file formats / Emulations ---> then any 32-bit executions or compiles will fail. Packages that will fail to compile include gcc, glibc and sandbox with very little meaning in the error message to indicate what the problem is. Reproducible: Always

People should read the FAQ we provide. We can't include everything from it in the handbook.
Should be mentioned under <title>Activating Required Options</title>
Can we also have a link to the FAQ in the handbook, thanks :)
Fixed in CVS, and no, the FAQ should not be linked in the handbook. We don't link other documents from within the flow of the handbook, because the handbook should only contain the essentials for installation. *Other material* is in *other docs* for that very reason.
