Except for legacy, build-tools, bootstrap-tools, and cross-tools, none
of /usr/include or /usr/local/include is supposed to be included. In
those phases though it is intended that /usr/include is used. Not
/usr/local/include though.
What package is providing /usr/local/include/libdwarf.h? 'pkg which
/usr/local/include/libdwarf.h' I ask so I can install it and recreate
the issue and fix it.
We likely just need to prioritize /usr/include over /usr/local/include
for these phases, which gcc49 may have backwards since it has its prefix
set to /usr/local from the ports build.
