ok, completely giving up on any hope of externally cross compiling a
different $arch I swtiched back to see if I could muddle through and get
amd64 to compile ON amd64 with lang/gcc49

did this http://www.freebsd.org/doc/en/articles/custom-gcc/article.html

Fails here:

===> lib/libproc (all)
make[5]: /usr/obj/home/sbruno/bsd/head/lib/libproc/.depend, 187:
ignoring stale .depend
for /usr/obj/home/sbruno/bsd/head/tmp/usr/lib/libstdc++.a
/usr/bin/ld: cannot find -lsupc++
cc: error: linker command failed with exit code 1 (use -v to see
invocation)
--- libproc.so.2 ---
*** [libproc.so.2] Error code 1

make[5]: stopped in /home/sbruno/bsd/head/lib/libproc


No idea what to do next.  I assume that this has worked in the past for
someone?
