You really want to use -isysroot =/usr/include. One issue the NetBSD
patches solves is that GCC seems to consider sysroot vs non-sysroot as
property for whether the default paths should be searched, which is
insane. The patches allow building a single GCC binary that can use
--sysroot ${DESTDIR} or not and will do the right thing..
