Like so?  I tried placing it next to the mcpu=power8 clause, but it seems
you cannot place comments there, as it creates syntax errors during the build.

 /* Common ASM definitions used by ASM_SPEC among the various targets for
    handling -mcpu=xxx switches.  There is a parallel list in driver-rs6000.c to
    provide the default assembler options if the user uses -mcpu=native, so if
-   you make changes here, make them also there.  */
