Any sub-makefiles would not have to specify those flags explicitly,
since they were added to ${CC} and ${CXX}.

But what I meant is that even if you specify those flags, the compiler
still searches for headers and libraries in the base system.  So if some
header is removed from /usr/src, for example, but is still available in
/usr/include, it can be erroneously picked up during buildworld.
