rs6000: Allow -mabi=no-altivec override on command line for AIX.
The override options machinery to set rs6000_altivec_abi for AIX
doesn't check if the option is set on the command line. This patch
checks for a command line option to not override it.
gcc/ChangeLog:
* config/rs6000/rs6000.c (rs6000_option_override_internal):
Don't implcitly enable Altivec ABI if set on the command line.
