# tools (linker, assembler, preprocessor, etc) without any indication that
# you cannot feed such options to the gcc driver directly.  (For example, the
# linker takes a -z option, but you must type -Wl,-z for gcc.)  Instead, we
# ask the driver ("g++") for the name of the compiler ("cc1"), and parse the
# --help output of the compiler.
