No.  I have just committed a fix for this.  Your patch does not replicate the
rs6000_isa_flags_explicit field to be a GCC option.  Presumably the intent of
the 57756 patch was to remove references to the global variables.  Your patch
still references those variables.  What I did was to move the isa explicit flag
to be a target variable, so that it is preserved in the gcc_options structure
like everything else.

However, I wonder why you committed the original changes with changes to the
powerpc backend, and DID NOT build a powerpc and fix the compilation errors.

	PR target/57756
	* config/rs6000/rs6000.opt (rs6000_isa_flags_explicit): Move the
	explicit isa flag to be an options variable, instead of using
	global_options_set.  Remove define from rs6000.h.
	* config/rs6000/rs6000.h (rs6000_isa_flags_explicit): Likewise.

	* config/rs6000/rs6000.c (rs6000_option_override_internal):
	Initialize rs6000_isa_flags_explicit.
	(rs6000_function_specific_save): Add gcc_options* parameter, so
	that the powerpc builds after the 2013-10-15 changes.
	(rs6000_function_specific_restore): Likewise.
