which when rebuilt in a powerpc64 context shows up with:

--with-local-prefix=3D/usr/local/lib/gcc/powerpc64-portbld-freebsd11.0/5.3=
.0
in the "Configured with" (from using -v):

[Despite some prior mis-wording in other messages: The line match for =
--with-local-prefix=3D 's value with "/include" appended matches the =
line prior to /usr/local/include in the search list, not the following =
line.]
So far I'm unsuccessful at avoiding /usr/local/include being in the =
search list. I'm still at the stage of C_INCLUDE_PAPTH and =
CPLUS_INCLUDE_PATH being the best means that I've found to force =
/usr/include based paths to win when there are conflicts in =
/usr/local/include from ports that have been built.
So far I'm only doing the experiment with devel/powerpc64-gcc (used as =
the so-called "cross compiler" in my powerpc64 self-hosted context), not =
with the lang/gcc49 that I use as the system compiler. For lang/gcc49 =
I'm still using C_INCLUDE_PAPTH and CPLUS_INCLUDE_PATH to avoid =
/usr/local/include based paths from finding files. In part this is =
because I expect port building problems if I use lang/gcc49 to build =
ports without lang/gcc49 having /usr/local/include implicitly. I do not =
use devel/powerpc64-gcc to build ports.
