…DIR=OFF
The problem is because libclang_rt.builtins-{arch}.a for all the arches will be
installed into the same folder with old compiler rt layout
(LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=OFF) and OHOS driver will get a wrong
library in this case. To fix the problem, `-ohos` suffix will be added to the
ohos builtin libraries search path.
Note: OHOS driver doesn't support the old layout, compiler-rt for
${arch}-linux-unknown-ohos targets have to be built with
LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON
