When I tried an rpi2 buildworld for clang380-import -r294609 it failed with
“relocation truncated” problems. (arm7-a cortex-a7 no misaligned accesses as my
context.)
It looks like this is from picking up base/head’s -r294499 as part of forming
-r294599 in clang380-import. -r294499 commented out having -mlong-calls in
/usr/src/lib/clang/clang.lib.mk:
