Subject: [PATCH] solenv: add COMPILER_EXTERNAL_TOOL

COMPILER_PLUGIN_TOOL has two effects:

1) It makes LinkTarget aware that no object code will be generated by
the compiler (as the compiler is just a tool, not a real compiler), so
e.g.  it's expected that no dependency output will be generated.

2) It puts some of the clang plugins into rewriter mode.

When using some external compiler tool (like a wrapper around
clang-rename), then 1) is wanted, but not 2), i.e. getting rid of the
dependency generation part is wanted, but none of the rewriter plugins
should be activated. So add COMPILER_EXTERNAL_TOOL that does 1) without
2).
