I'm sure this isn't right.  cmm-suffix-rules.mk is for rules for 
building .cmm files.  Also, in hs-suffix-rules-srcdir.mk we already have:

$1/$2/build/%.$$($3_osuf) : $1/$4/%.hc includes/ghcautoconf.h 
includes/ghcplatform.h | $$$$(dir $$$$@)/.
	"$$(CC)" $$($1_$2_$3_ALL_CC_OPTS) -Iincludes -x c -c $$< -o $$@

$1/$2/build/%.$$($3_osuf) : $1/$2/build/%.hc includes/ghcautoconf.h 
includes/ghcplatform.h
	"$$(CC)" $$($1_$2_$3_ALL_CC_OPTS) -Iincludes -x c -c $$< -o $$@

# $1/$2/build/%.$$($3_osuf) : $1/$2/build/%.$$($3_way_)hc
# 	"$$($1_$2_HC)" $$($1_$2_$3_ALL_HC_OPTS) -c $$< -o $$@
#
# $1/$2/build/%.$$($3_osuf) : $1/$2/build/%.hc
# 	"$$($1_$2_HC)" $$($1_$2_$3_ALL_HC_OPTS) -c $$< -o $$@
#
# $1/$2/build/%.$$($3_way_)s : $1/$2/build/%.$$($3_way_)hc
# 	"$$($1_$2_HC)" $$($1_$2_$3_ALL_HC_OPTS) -S $$< -o $$@


There are already some problems with these rules:

  (1) hard-coded dependencies on ghcautoconf.h and ghcplatform.h
  (2) hard-coded -Iincludes

and the second commented-out rule appears to be a duplicate of the 
second uncommented rule.

This all needs cleaning up.
