rs6000: Fix an error message in sysv4.h

While looking at PR82411, I got the error message

	error: '-msdata=-mcall' and 'eabi-linux' are incompatible

which caused some head-scratching.


	* config/rs6000/sysv4.h (SUBTARGET_OVERRIDE_OPTIONS): Correct error
	message for incompatible -msdata=* and -mcall-* options.
