Issue Description:

I am trying to build swift from sources on Gentoo linux.
Running script utils/build-script --preset=buildbot_linux install_destdir=$PWD/swift_inst installable_package=$PWD/swift-gentoo.tar.gz
I have got an error:

    • Found LLVM_CONFIG as /usr/bin/llvm-config
      llvm-config: sources not installed, --src-root not available

    • /usr/bin/llvm-config --assertion-mode --bindir --libdir --includedir --prefix --src-root
      CMake Error at cmake/modules/LLDBStandalone.cmake:44 (message):
      llvm-config failed with status 1
      Call Stack (most recent call first):
      CMakeLists.txt:3 (include)

    • Configuring incomplete, errors occurred!

Please see the attached build log for more details.
It looks like that the build script took llvm-config from the host but not from swift build directory. Host llvm-config returns empty --src-root because Gentoo does not install LLVM sources and I think it is logic.

Simple workaround is to temporary rename host llvm-config and to remove lldb-linux-x86_64 directory from ... build/buildbot_linux.
In this case the build script will use just build LLVM.
According to the build log the script still uses host clang which is outdated. I do not know yet is it acceptable?

I did clone everything today and repeated the build. The problem is disappeared so I close the issue. Thank you.
