[RFC 0/4] Oe-selftest for Clang, LLVM, LLD

[Deepesh.Varatharajan@windriver.com]

From: Deepesh Varatharajan <Deepesh.Varatharajan@windriver.com>

This patch series introduces a test framework to run selftests for both
native and target builds of Clang, LLVM, and LLD.

Summary of changes: 
-Patch 1: Disable clang-tools-extra tests because Clang's CMake cannot 
          see the llvm-bcanalyzer target.
-Patch 2: Enabled the required CMake flags for clang, llvm & lld tests
-Patch 3: Selftest script for Clang, LLVM, and LLD including exclude list
-Patch 4: Fix rust build failure by replacing target llvm-config with native

Testing:
1. The test suite has been successfully validated on x86-64, arm64, riscv64,
and arm32 for all three components.
2. Clang, LLVM & LLD all together ~80K tests are there and we currently 
~200 tests to exclude list which are failing (0.25%).

WIP:
LLVM target tests are currently failing on x86. This is under investigation
and will be addressed

Deepesh Varatharajan (4):
  clang-tools-extra: disable tests
  clang: Enable tests for llvm, clang, lld
  oeqa/selftest/clang: Add selftest for Clang/LLVM/LLD
  rust: Fix rust build failure
