Actually, at first, FHS says that any /lib<qual> would be allowed, but
it then goes into specifics in Chapter 6, Operating System Specific
Annex. Under the heading "/lib64 and /lib32 : 64/32-bit libraries
(architecture dependent)", it says, "The 64-bit architectures PPC64,
s390x, sparc64 and AMD64 must place 64-bit libraries in /lib64, and
32-bit (or 31-bit on s390) libraries in /lib."

Personally, I do have a ~amd64 Gentoo chroot with LIBDIR_x86="lib".
There is only one place that I've found that it is still broken, namely
one line in toolchain.eclass (patch attached). I've been meaning to file
a bug for quite a while now, but never got around to it.
