Subject: [PATCH] INIT/cc.darwin: suppress another annoying compiler warning

src/cmd/INIT/cc.darwin:
- Since the flags added from Apple's ksh-27.tar.gz Makefile
  explicitly redefine a macro, let's disable the warning on
  redefined macros.

(cherry picked from commit 4b21a0abce8406e82d3afa4a68ef6bb56d98c797)
