GCC does still have a pdp11 backend today.  It doesn't seem to be very
actively maintained, and how well it works nowadays is possibly another
question, but it should at least be buildable.

I'm not sure there ever was such a switch.  If there was, it was
removed a long time ago.  "-std=c90" still works and should accept
some, maybe most, K&R code.  As others have noted, GCC has no option to
accept pre-K&R C, though I suspect it would probably not be all that
hard to write some sort of preprocessor to convert such code to either
K&R or C90 dialect.
