Given the views expressed by target maintainers I've applied this patch to document the ARM and MIPS config-ml.in options as obsolete (with the expectation that they will be removed later in the 4.7 release cycle). I'd still encourage maintainers for the other targets with such options in config-ml.in to move the option implementations to config.gcc as a better place to implement such options, if they think the options are still useful.
