This would be a good idea, but other CFLAGS options may be needed
for some ports, in particular a different optimization option. So,
it is important that CFLAGS is built in a consistent order.

IMHO, to avoid problems, MacPorts should have a default CFLAGS value,
e.g. "-O -g" (as suggested by Apple). Then there should be a command
to append options to CFLAGS before calling configure, e.g.
configure.cflags-append. The universal variant should have
configure.cflags-append \
  "-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc"
and the portfile could add other options if need be. Perhaps ditto
for LDFLAGS. This way, there shouldn't be any problem with overridden
CFLAGS/LDFLAGS.
