Prevent "undef var" errors on gcc --help or --version with self-specs
* gcc.c (spec_undefvar_allowed): New global.
(process_command): Set to true when running for --version or --help,
alone or together.
(getenv_spec_function): When the variable is not defined, use the
variable name as the variable value if we're allowed not to issue
a fatal error.
