Unfortunately current behaviour makes problems for clang-tools like clang-tidy and clangd that read CDBs from `compile_commands.json`. They start looking headers relative to compiler path specified in CDB but it is better to use path specified in -isysroot (it is what user expects when they specify the option). What is the rationale behind ignoring `-isysroot` specified in command line? If user would like to use search path relative to compiler, they could just remove `-isysroot` and get this behaviour.
