Deprecating config-ml.in multilib selection options

[Joseph S. Myers]

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.
