[PATCH] D131665: [CMake] Support passing arguments to build tool (bootstrap).

[Carlos Alberto Enciso via Phabricator via cfe-commits]

CarlosAlbertoEnciso added a comment.

To give more scope to the reviewers, the following CMake options illustrate the benefit of this patch.

For example, if I want to do a dry run on stage-2, I will pass `-DLLVM_EXTERNAL_PROJECT_BUILD_TOOL_ARGS="-n --verbose"`

  -DCLANG_ENABLE_BOOTSTRAP=ON -DLLVM_ENABLE_PROJECTS=clang -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD=X86 -G"Ninja" -DLLVM_EXTERNAL_PROJECT_BUILD_TOOL_ARGS="-n --verbose"

When `ninja` builds `stage-2` it receives the additional `-n` and `--verbose` options.

The `build_tool_args` passed to `BUILD_COMMAND` looks like:

  '--;-n;--verbose'
