【问题描述】：
我想用 yocto 构建 core-image-minimal，但它失败了。要设置所有内容，我使用以下步骤：
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect cmake
git clone git://git.yoctoproject.org/poky.git poky.git
cd poky.git
git checkout -b morty remotes/origin/morty
. oe-init-build-env
cd ..
git clone https://github.com/altera-opensource/meta-altera.git meta-altera
cd meta-altera
git checkout -b angstrom-v2015.12-yocto2.0 remotes/origin/angstrom-v2015.12-yocto2.0
然后我将meta-altera 的路径添加到build/conf/bblayers.conf 和MACHINE = "cyclone5" 到build/conf/local.conf。我希望，现在bitbake core-image-minimal 会运行，但它会因以下错误而停止：
WARNING: qemu-native-2.7.0-r1 do_populate_sysroot: File '/mydirectory/poky.git/build/tmp/sysroots/x86_64-linux/usr/share/qemu/openbios-ppc' from qemu-native was already stripped, this will prevent future debugging!

我通过将INSANE_SKIP_qemu-native = "already-stripped" 添加到poky.git/meta/recipes-devtools/qemu/qemu.inc 来消除警告，但错误仍然存在。我使用 Ubunut 16.04 作为我的构建机器。感谢您提供任何帮助或提示。
如果我继续构建，我会在构建 gcc-runtime-6.2.0-r0 do_compile 时收到错误并停止。我假设这个错误是基于 qemu 错误。
这是 bitbake 中显示的构建配置：

BB_VERSION = "1.32.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "universal"
TARGET_SYS = "arm-poky-linux-gnueabi"

DISTRO = "poky"
DISTRO_VERSION = "2.2.1"

TARGET_FPU = "hard"

meta-poky
meta-yocto-bsp = "morty:924e576b8930fd2268d85f0b151e5f68a3c2afce"

错误信息表明有东西试图剥离“palcode-clipper”文件。这是 Alpha 模拟器的固件 blob，因此它是一个 Alpha ELF 文件。因此，工具链条（可能是 ARM）合理地抱怨它无法处理它。问题在于不加选择地试图在它可以找到的每个二进制文件上运行“剥离”——你应该找到它并让它做一些更聪明的事情。
