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 is being used as the C compiler.]
=============
[CXX=clang++]: [clang++ is being used as the C++ compiler]
=============
[gcc: error: unrecognized command-line option â--config=/usr/lib/rpm/redhat/redhat-hardened-clang.cfgâ]: [This is the error message from the build failure.]

Issue: The rpm set clang as the C compiler, but the build system hard-coded gcc as the compiler, so it fails because it is trying to use a command line argument that is meant for clang.
Resolution: Fix the package's build system so that it respects the CC environment variable and doesn't hard-code gcc.
