[yocto] Patch failures

[Paul D. DeRocco]

I'm trying to migrate an Atom-based build from Fido to Morty, and also
switch from 32-bit mode to x32. On a clean build, it gets about half way
through, and then suddenly coughs up a patch error. I've put blank lines
between the log lines so that the email word wrap won't be as confusing:

--

If I start bitbake again, it detects a "fence", and proceeds a little
further. I can do it over and over again, and it keeps building more and
more, but this can't be right, can it? The strange thing is that the
patches are all about ARM, PowerPC, etc., which have nothing to do with my
system. Could this be some fundamental misconfiguration having to do with
my MACHINE? At the beginning of my local.conf, I have:

	MACHINE ?= "chroma-bsp"
	DEFAULTTUNE = "core2-64-x32"
	baselib = "libx32"

where chroma-bsp is defined in my own layer. My chroma-bsp.conf file
contains (among other things):

	PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto-rt"
	PREFERRED_VERSION_linux-yocto-rt ?= "4.8%"
	require conf/machine/include/tune-atom.inc
	require conf/machine/include/x86-base.inc

I'm not really good at this. Does anyone see anything wrong?
