 | ./configure
Two problems:
1) This requires you to export two variables into the outer shell's
 environment. As a general rule, I think this is a bad idea for
 tricking configure. What else might you be affecting? Others
 might not care as much.
2) Any time you overload a make variable that has existing semantics,
 you have to worry about losing the original value. Personally, I
 think it's easier to get CC overloading right than get OPT or
 CFLAGS overloading (and easier than getting them both right). But
 maybe that's just me.
