From: Peter Tatrai <peter.tatrai.ext@siemens.com>

The LLVM, Clang and LLD oe-selftests are currently not practical to run on
qemuppc.

qemuppc uses the QEMU mac99 machine, which only supports a single CPU and
has a RAM limit below the test's current defaults. To boot the test image at
all, the test would need qemuppc-specific resource handling, reducing the QEMU
SMP setting from 4 to 1 and lowering the requested memory.

Even with those adjustments, the test run is not useful in practice on
32-bit PowerPC: running the clang/llvm lit suites with a single vCPU takes
many hours, and the run still ends with a consistent set of failures in
clang-repl / LLVM ORC JIT related tests. Those would need to be added to the
excluded tests for this target before the suite could pass.

Rather than carrying qemuppc-specific resource handling plus an additional
set of JIT-related exclusions for test runs that are prohibitively slow, skip
these LLVM, Clang and LLD test suites on qemuppc for now.
