<pre>hi,
the clang-8 reports errors during sanitizers crosscompilation (host:
x86_64-linux-gnu, target: aarch64-linux-gnu). looks like a missing --target
option for some sources or bad source selection. full configure/build log
attached.
(...)
-- Compiler-RT supported architectures: aarch64
(...)
-- Builtin supported architectures: aarch64
