Comment (by kencu):

 we have {{{gcc}}} specifically configured to do this on purpose:
 {{{
 --with-local-prefix=/opt/local
 }}}

 See <https://gcc.gnu.org/install/configure.html>.

 I suppose we could debate why that is -- none of the clangs are built that
 way, and we pass {{{-I${prefix}/include}}} all the time anyway, or else
 the clang's would not work.

 Dunno who decided we needed to do this, or how many years ago that
 happened...
