The previous logic assumed that if $BUILD_IMAGES_FROM_FEEDS=1 then a
complete set of ipk feeds from which to build the image is already
present under $IPK_FEED_URIS at do_rootfs runtime.
$IPK_FEED_URIS usually contains "file://${DEPLOY_DIR_IPK}" which
renders the above assumption bad because some recipes in the current
build can contain code like do_install[nostamp] = "1" which will cause
rebuilds bumping $PR and invalidating the index.
Even when the index is manually re-created before an image build
("bitbake package-index"), the nostamp will cause failures because the
dependency gets rebuilt before do_rootfs in the "bitbake <image>" call.
So make the opkg rootfs index logic the same as for rpm/deb, to always
update the index in $DEPLOY_DIR_IPK to fix the above nostamp failure.
Feeds outside $DEPLOY_DIR_IPK added to $IPK_FEED_URIS continue to work
as usual, for eg. by using a http:// URI.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
