Makefile.common has 

# to make srpms on F-11 and newer for older releases use old hashes
# F-10's rpm supports both styles F-9 is the only current release
# outside of rhel that needs old hasnes
ifeq ($(DISTVAR),rhel)
RPM_DEFINES := $(RPM_DEFINES) \
                --define "_source_filedigest_algorithm md5" \
                --define "_binary_filedigest_algorithm md5"
endif
ifeq ($(DISTVAL),9)
RPM_DEFINES := $(RPM_DEFINES) \
                --define "_source_filedigest_algorithm md5" \
                --define "_binary_filedigest_algorithm md5"
endif


this will allow you to create useable srpms   with make srpm   for scratch 
building
