It's only ports binutils and ports gcc that search /usr/local.

I used to think this too, but now I think it should be possible to use
any compiler to compile something from base or something that should only
depend on things from base, for testing purposes or perhaps because it
needs to be deployed on some other machine.  Compilers shouldn't search
/usr/local implicitly then.  It's easy enough to add -I and -L flags
(perhaps using pkg-config) but it's not easy to remove built-in -I and
-L flags.
