I've done buildworld buildkernel for -r301975 on an rpi2 (not using  WITH_META_MODE=yes) with no problem. The rpi2 was already running -r301975 via a amd64 -> rpi2 cross build.

You do not mention what vintage of 11.0 your -r301974 build was started from. A

uname -apKU

output would be appropriate to post as one way of indicating that.

My WITH_META_MODE=yes buidlworld buildkernel is still in process.

Later below list my src.conf showing my slightly odd choices targeting armv7-a/cortex-a7 explicitly. I'd be surprised if that makes a difference for this issue. You have not provided your src.conf or make.conf or other such context.

My -r301975 cross builds on amd64 targeting an rpi2 [armv7-a/cortex-a7] have all worked fine (no matter if WITH_META_MODE_yes was in use or not).

I've only used the system clang 3.8.0 to target armv6 in modern times.

My src.conf for rpi2 self hosted builds looks like:

> TO_TYPE=armv6

The ~/src.configs/make.conf is empty.

The amd64 -> rpi2 cross builds are only different for src.conf by:

> # diff ~/src.configs/src.conf.rpi2-clang-bootstrap.rpi2-host ~/src.configs/src.conf.rpi2-clang-bootstrap.amd64-host

Showing the "on a rpi2" script that runs make for using WITH_META_MODE=yes :

> # more ~/sys_build_scripts.rpi2-host/make_rpi2_nodebug_clang_bootstrap-rpi2-host.sh 
> kldload -n filemon && \
> script ~/sys_typescripts/typescript_make_rpi2_nodebug_clang_bootstrap-rpi2-host-$(date +%Y-%m-%d:%H:%M:%S) \
> env __MAKE_CONF="/root/src.configs/make.conf" SRC_ENV_CONF="/root/src.configs/src.conf.rpi2-clang-bootstrap.rpi2-host" \
> WITH_META_MODE=yes \
> MAKEOBJDIRPREFIX="/usr/obj/clang/arm.armv6" \
> make $*

My /usr/src tree has some changes/additions --but mostly for powerpc64 and powerpc issues:

(The include/include ones are from something making links pointing back up to the parent include/ . I did not explicitly create these.)

(The cxbg and cxbge ones were from trying to have amd64 target amd64 via xtoolchain (devel/amd64-gcc). But other places also stopped it and I quit trying that for now.)
