[Context basics: projects/clang380-import -r295351 for buildworld/buildkernel that targeted an rpi2 (armv7-a/cortex-a7).]

When I attempt portinstall/portmaster builds for misc/raspberrypi-userland I get the following.

. . .

which stops the overall build.


There are also some reports like:

(I will not list all of them.)

Stop reading the description here if you do not care about supporting details at this point.

(In case it is not clear: This is clang 3.8.0 that is in use. It was used for buildworld and buildkernel as well.)
