How about appending to CC1_SPEC?

-#ifndef CC1_SPEC
+#undef CC1_SPEC
 #define CC1_SPEC "\
 %{gline:%{!g:%{!g0:%{!g1:%{!g2: -g1}}}}} \
 %{G*} %{EB:-meb} %{EL:-mel} %{EB:%{EL:%emay not use both -EB and -EL}} \
 %{save-temps: } \
-%(subtarget_cc1_spec)"
+%(subtarget_cc1_spec) %{profile:-p}"
-#endif

Other architecture seems to set %{profile:-p} to CC1_SPEC.
