rs6000.opt (rs6000_ieeequad, [...]): Remove TargetVariable entries.

Browse Source 
* config/rs6000/rs6000.opt (rs6000_ieeequad, rs6000_altivec_abi,
	rs6000_spe_abi, rs6000_darwin64_abi): Remove TargetVariable
	entries.
	(mabi=): Replace with separate entries for mabi=altivec,
	mabi=no-altivec, mabi=spe, mabi=no-spe, mabi=d64, mabi=d32,
	mabi=ieeelongdouble and mabi=ibmlongdouble.
	* config/rs6000/rs6000.c (rs6000_option_override_internal): Move
	check for -mabi=spe without SPE ABI support here.
	(rs6000_handle_option): Replace OPT_mabi_ handling with
	OPT_mabi_altivec and OPT_mabi_spe handling.
