If "64-bit PC" is too vague, the alternative designator for the amd64 arch
is the vendor neutral "x86-64".  The vendor-neutral designator for all of
i386, i486, i586, i686, amd64 and x32 is "x86" (i.e. it is for both 32-bit
and 64-bit).  i286, i186 and 8086 are too old to bother with :-)

AFAIK, "x86-32" is seldom used.  "x64", which is the same as "x86-64", is
very rarely used (in fact, I've never seen anyone use it in Linux-centric
communities and workplaces).

AFAIK, the full x86 arch list, with vendor-neutral names is:

(non-vendor-neutral/explanation): vendor neutral
IA32,ix86,i386..i686:           x86-32
amd64/EM64T, 64-bit ABI         x86-64
32-bit ABI for amd64/EM64T:     x32
any of those:                   x86


1. x32 is very different from x86-32.  x32 requires the x86-64 instruction
   set and register set, and a x86-64 64-bit kernel with x32 support.  There
   is no non-vendor-neutral name for x32, fortunately :-)

2. A x86-64 processor can run code for any x86 arch/ABI.

3. A recent x86-64 linux kernel, properly configured, is supposed to support
   all three arches/ABIs (x32, x86-32 and x86-64) concurrently.
