cross building ruby2.3
After appending :native to the Build-Depends: ruby, the only missing piece to satisfying Build-Depends is openssl. It is not clear whether openssl should be Multi-Arch: foreign. If it should, ruby2.3 should do nothing about it. If it shouldn't, ruby2.3 Build-Depends: openssl should gain :native as well.
Building fails somewhere during make install. While the build is verbose installation isn't. Fix:
sed -i -e '/MAKE.*install/s/$/ V=1/' ruby2.3-*/debian/rules
The actual issue happens in ext/ripper where the all target depends on check. Apparently check is run with RUBY set to the host arch ruby, which fails. The build succeeds when skipping the check target (but it is not clear whether the results are good).
Notes
to cross build, use sbuild --host=${foreign_arch}
