This would solve https://github.com/apt-itude/rules_pip/issues/46

I can do the work and try and fix this in this repo, but could use some pointers

@leodido can't add you to reviewers

@leodido it changed a lot in the .go file. Is this error output the reason? ``` [bmatase@bmatase-mbp go-syslog (fix-global-var-race)]$ make build ragel -I common -Z -G2 -e -o rfc5424/builder.go rfc5424/builder.go.rl...

I see the problem. Working on fixing it

@leodido had some trouble with the `-i` aka inplace flags on my mac but I think it is in good shape now

@leodido I believe I've addressed the changes you requested. Let me know if there is anything else you spot
