[PATCH] docs: $arch does not map 1:1 to uname(2) arch. BZ 1003554

> Unable to access the referenced bug, but:

Basically ppl complain that $arch != os.uname()[4], although
it's clearly documented to be the same.. For x86_64 arches
$arch == amd64 or ia32e, depending on the vendor.

Hmm, so just kill the uname() note then?
