Amurray was so kind to point out that we already do not use it on -m32

/* Enable code instrumentation of control-flow transfers.
   Available on x86 and x86_64.  */
#ifndef CF_PROTECTION_SPEC
# ifdef DIST_DEFAULT_CF_PROTECTION
#  define CF_PROTECTION_SPEC " 
%{!m32:%{!fcf-protection*:%{!fno-cf-protection:-fcf-protection}}}"
# else
#  define CF_PROTECTION_SPEC ""
# endif
#endif

And that maybe it would need to be:

#  define CF_PROTECTION_SPEC " %{!m16:%{!m32:%{!fcf-protection*:%{!fno-
cf-protection:-fcf-protection}}}}"
