  10 # compilers will run on. For instance, "ppc i386". If the current machine
  11 # isn't in the list, it will (effectively) be added.

  14 # The second parameter is a space-separated list of the architectures the
  15 # compilers will generate code for. If the current machine isn't in the list, a
  16 # compiler for it will get built anyway, but won't be installed.

  29 # built.

  33 # unstripped executables and generated source files) helpful in debugging the
  34 # resulting compiler.
