gcc 3.2's cpp breaks configure scripts

[Miles Bader]

I think /usr/local is well established as `a standard hierarchy that
overrides /usr', and so gcc should _definitely_ search /usr/local/include
before /usr/include -- many people depend on this behavior.

If you have a more complex installation that breaks (e.g., multiple local
versions of gcc installed), it's up to you to figure out a way to fix it, not
the great majority of people that use /usr/local only.
