From: Mingli Yu <mingli...@windriver.com>
Now the QEMU_TARGETS used to set the supported built qemu targets
both for "bitbake qemu-native" and "bitbake qemu".
After the qemu package installed on the target, it will take up
464M which includes not only the one matches the arch of the target
but aslo all available built qemu targets which set by QEMU_TARGETS.
Making "bitbake qemu" to only build the arch matches the target should
satisfy our usual need and ease the concerns who cares much about the
size in embedded device as it decreases the qemu rpm size from about 65M
to about 17M and the size of the extracted qemu RPM decreased from
about 464M to about 248M.
