We want to hook `gcc -fanalyzer` on `clang` if `clang` is used as the system compiler. However, it does not make sense to hook GCC Analyzer on `clang --analyze`, which is invoked by `csclng` while wrapping `gcc` as the system compiler. Apart from wasting resources by running multiple processes of GCC Analyzer in parallel, this was causing unnecessary noise in `scan.log` as GCC Analyzer complained about unsupported flags, which were injected by `csclng` for `clang --analyze` only: ``` gcc: error: unrecognized command-line option ‘-fno-caret-diagnostics’ gcc: error: unrecognized command-line option ‘-fno-caret-diagnostics’ gcc: error: unrecognized command-line option ‘-fno-caret-diagnostics’ ``` Reported-by: Lukáš Zaoral Fixes: commit 983b895 Related: csutils#43 Closes: csutils#44
