At least CFLAGS and very likely CPPFLAGS. There are also things like
-m32 or -Dconst= (for ACK) or -Xa (SINIX) or -YPOSIX that can change
things, and probing something about CC is effectively always at least
compiling a test program except for very few very brittle things (in
my vast porting experience, I gave up trying to do so without passing
a test program that just returns 0).
