MacOS Errors

[stahnma]

I've been trying to build a few things using rubyc on MacOS in the last couple days and getting symbol linking issues.

I'm on Sierra 10.12.6.

generating enc.mk
making srcs under enc

This attempt was to build rubyc from master.

bin/rubyc -c bin/rubyc

Can you run xcode-select --install then retry running rubyc?

This seems to be a cross-project issue: https://github.com/rbenv/ruby-build/issues/1133#issuecomment-331498031
