I use tc-build from the ClangBuiltLinux project to build a selfmade
x86-64 LLVM toolchain.

My invocation looks like this:

$ python3 ./build-llvm.py --no-update --build-type Release -p
clang;lld -t X86;BPF --clang-vendor dileks -B
/home/dileks/src/llvm-toolchain/build -I /opt/llvm-toolchain
--check-targets clang lld --build-stage1-only --install-stage1-only -D
LLVM_PARALLEL_LINK_JOBS=1 --show-build-commands

The LLD check-targets failed:

3887:******************** TEST 'lld :: ELF/compressed-debug-input.s'
FAILED ********************
3918:******************** TEST 'lld ::
ELF/compressed-debug-input-err.s' FAILED ********************

$ grep error: log_tc-build.txt

This is due to I have no ppc target:

$ /home/dileks/src/llvm-toolchain/build/stage1/bin/llvm-mc --version
LLVM (http://llvm.org/):
 LLVM version 13.0.0
 Optimized build.
 Default target: x86_64-unknown-linux-gnu
 Host CPU: sandybridge

 Registered Targets:
   bpf    - BPF (host endian)
   bpfeb  - BPF (big endian)
   bpfel  - BPF (little endian)
   x86    - 32-bit X86: Pentium-Pro and above
   x86-64 - 64-bit X86: EM64T and AMD64

I needed to apply [1] to fix the issue with LLD check-targets:

Please cherry-pick this to release/13.x Git tree.
