Hi,

the build of ruby 2.3.3 fails on NetBSD/macppc (which is a powerpc architecture) with

Stop.

Compiling miniruby with -g and running the same command reveals where the
SEGV is triggered:

{62} gmake -n encdb.h
echo generating encdb.h
./miniruby -I./lib -I. -I.ext/common  ./tool/generic_erb.rb -c -o encdb.h ./template/encdb.h.tmpl ./enc enc

Suggestions for what to dig out next would be appreciated, ruby is
unknown ground for me.

The only slightly "odd" thing with NetBSD/powerpc is that it's big-endian.
