Update to v4.1.0. Also includes other major packaging changes as follows: There is a new package maintenance workflow - see README.PACKAGING for details. The sibling packages qemu-linux-user and qemu-testsuite are now created with the Build Service's MultiBuild feature. This also necessitates combining the qemu-linux-user changelog content back into qemu's. Luckily the delta there is quite small. Note that the qemu spec file is now that much busier, but added section markers should help reduce the confusion. Also qemu is being enabled for RISCV host compatibility, so some changes are related to that as well.

Fedora 17 for ARM reads /proc/cpuinfo and fails if it doesn't contain
|
|
ARM related contents. This patch implements a quick hack to expose real
|
|
/proc/cpuinfo data taken from a real world machine.
|
|
|
|
The real fix would be to generate at least the flags automatically based
|
|
on the selected CPU. Please do not submit this patch upstream until this
|
|
has happened.
