ignore this, it's complaining about the ` /usr/bin/as: unrecognized
option '-mpower4'` at the bottom, it's a known issue.

I'd rather not blacklist it. So it looks like we don't see this in
our CI (example:
https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/jobs/301119543).
It seems related to which config you compile with. With the attached
config, I was not able to reproduce:

$ gunzip config.gz
$ cp config .config
$ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make CC=clang -j71
olddefconfig # note this shouldn't be needed
$ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make CC=clang -j71
scripts/mod/empty.o

Doesn't produce anything, no error from make about being an invalid
target, but also no -mpower4 warning. I also don't understand why the
provided config doesn't set or unset many configs in linux-next.

Can you please triple check? I want to make sure the steps to
reproduce are reproducible.

'powerpc-defconfig' doesn't seem to be a named config. Seems I must
use the attachment?

Hi Philip, I tried the above commands to reproduce, but I see:

$ COMPILER=clang make.cross ARCH=powerpc
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13:
Permission denied)
E: Unable to acquire the dpkg frontend lock
(/var/lib/dpkg/lock-frontend), are you root?
cross tool binutils-powerpc-linux-gnu install failed
Please ensure powerpc cross tools has been installed.
Please install: xz-utils lftp
Install clang compiler failed
setup_crosstool failed
$ sudo apt install binutils-powerpc-linux-gnu
binutils-powerpc-linux-gnu is already the newest version (2.33.1-2).

Should install_cross_packages() check for these first, instead of
always trying to install them?

Check build log, we missed CROSS_COMPILE when make prepare

```

/usr/bin/timeout -k 100 2h /usr/bin/make HOSTCC=clang-11 CC=clang-11
-j32 -C source O=/kbuild/obj/consumer/powerpc-lyd-reproduce ARCH=powerpc
prepare

Reproduce it locally.

```
