Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

  [CC=clang]: [clang has been selected as the default C compiler.]
=============
[CXX=clang++]: [clang++ has been selected as the default C++ compiler.]
=============
[CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:67 (message):
  The C compiler

    "/usr/bin/clang"

  is not able to compile a simple test program.

  It fails with the following output:

    ninja: build stopped: subcommand failed.]: [This is the error message that describes the failure.]


Answer: Issue: The build failed, because the RPM was being built with LTO, but ld.bfd could not find the LLVMgold.so plugin which is used for linking LTO bitcode files together.
Resolution: This is likely a bug in llvm, please file an issue.
