Uhmm, I could have sworn that I had needed -Wp,-U... for the -Wp-D...
and -U for the -D when I was fixing the test builds but you're right,
simply -Wp,-U_FORTIFY_SOURCE -Wp,-D_FORTIFY_SOURCE=3 appears to work
for both -D_FORTIFY_SOURCE=2 as well as -Wp,-D_FORTIFY_SOURCE=2.  I'll
test this some more and post a PR for redhat-rpm-config.

Thanks,
Sid
