Lazy expansion is true, but the reason we did ALL_CFLAGS was to make CFLAGS overridable from the command line.

I suspect that this would currently fail to add -I/some/where/include on the compilation command line:

	make CFLAGS='-Os -g' CURLDIR=/some/where
while CURL_LIBCURL is set correctly on the linkage command line.
