OK, looks like if I have /opt/netbsd/script directory first in my PATH
then all is good:

ls -l ./pkgtools/cwrappers/work.rp3/.gcc/bin/
total 0
lrwxr-xr-x  1 root  wheel   3 Sep 17 17:23 c++ -> g++
lrwxr-xr-x  1 root  wheel   3 Sep 17 17:23 cc -> gcc
lrwxr-xr-x  1 root  wheel  23 Sep 17 17:23 g++ -> /opt/netbsd/scripts/g++
lrwxr-xr-x  1 root  wheel  23 Sep 17 17:23 gcc -> /opt/netbsd/scripts/gcc

So why does it matter if gcc executable is in the path, when the
full path is explicitly set in mk.conf?
