You can probably stick that line above into an early-expanded diversion
such as INIT_PREPARE, but none of those are documented, so you'd be
treading in dark waters there.
A probably cleaner alternative would be to let your macro do all of
LX_CFLAGS=${CFLAGS-NONE}
AC_PROG_CC
rest of your old macro
and document that.
FWIW, gnulib solves things like this by having two (sets of) macros:
one FOO_EARLY and one FOO_... macro. That's not too bad, either.
Cheers,
Ralf
