I habitually do something like this anyway (duplicated for every
variable I mangle in configure):

orig_CFLAGS="$CFLAGS"

[detect some stuff...]

CFLAGS="$foo_CFLAGS $bar_CFLAGS $orig_CFLAGS"

[detect some more stuff...]

CFLAGS="$foo_CFLAGS $bar_CFLAGS $baz_CFLAGS $orig_CFLAGS"

Since that's the only sane way I can come up with to make
'CFLAGS=foo ./configure' work, and still keep a complicated configure.ac
readable. So I'd just AC_SUBST(orig_CFLAGS) and stuff that into
DISTCHECK_CONFIGURE_FLAGS, under the assumption that the configure
script is supposed to sort it out given that input.
