Ok, it seems like we've come full circle.  :-)  I'm once again back at
include failures, for libstdc++:

make -s xdev MAKEOBJDIRPREFIX=/var/tmp XDDESTDIR=/var/tmp/mips_cc
XDEV=mips XDEV_ARCH=mips WITHOUT_CLANG=t WITHOUT_CLANG_BOOTSTRAP=t
WITH_GCC=t WITH_GCC_BOOTSTRAP=t WITH_GNUCXX=t
...

===> gnu/lib/libstdc++ (obj,depend,all,install)
