[PATCH 1/2] qemux86: use a Core 2 Duo CPU instead of the original circa-1993 Pentium

[Alexander Kanavin]

This matches what the qemux86_64 is currently using, and
will allow testing the instructions added in the meantime;
particularly various SSE extensions are now enabled.

[PATCH 2/2] packagegroup-self-hosted: drop epiphany

[Alexander Kanavin]

Originally a web browser was added to build-appliance-image to
enable Hob's use cases that involve opening a URI; with Hob long gone,
a web browser is no longer necessary to have in build-appliance-image.

This will also address the out-of-resources problem when
build-appliance-image builds itself in a VM, as a test case.

While I like this change I also worry if we are leaving out any significant
x86 implementation out there in embedded space x86-64 is relatively newer
compared to 32 bit which was long stable

core2duo isn't exactly a modern chipset though, first released in
2006.  Does anyone *know* of any significant 32-bit x86 deployments
which are using significantly older hardware?

Putting my Intel hat on, we don't use these BSPs.  meta-intel ships
its own 32-bit and 64-bit machines.

Note that the 32 bit machine from meta-intel has actually been using
core2-32 tune for a while, so we are simply catching up here.

Sounds good then unless someone else has more

Intel Quark and AMD Geode LX are still available to buy today
(Geode for at least 2 more years).

I think they have their own BSP layers, so they lose out on least
common denominator here. I don't have strong objection to that, given
that using core2 is going to enhance our testing coverage quite a bit.

There is some kind of bad assumption somewhere in the sdk/mingw code:

https://autobuilder.yoctoproject.org/typhoon/#/builders/83/builds/152

and another glitch somewhere in the SDK code:

https://autobuilder.yoctoproject.org/typhoon/#/builders/59/builds/588

I was also worried that:

http://git.yoctoproject.org/cgit.cgi/yocto-autobuilder-helper/tree/scripts/publish-artefacts
may need fixes but it looks like it might be ok.

Cheers,

Richard

Seems like packagegroup-cross-canadian is erroneously taken from
sstate, instead of being repackaged when TUNE_ARCH changes but MACHINE
does not. I will send a fix in a moment, even though I am not totally
sure if it's the correct one.
