Issue Description:

Steps to reproduce:

1. Clone this repo: https://github.com/LuizZak/SwiftRewriter
2. Checkout the branch 'swift5.0'
3. Compile with 'swift build -c=release'

Expected result:

Have the project compile successfully.

Actual result:

Compilation fails with a linker error:

Undefined symbols for architecture x86_64:
  "_$s6Antlr46ParserCACycfC", referenced from:
      _$s15ObjcParserAntlr16ObjectiveCParserCN in ObjectiveCParser.swift.o
      _$s15ObjcParserAntlr022ObjectiveCPreprocessorB0CN in ObjectiveCPreprocessorParser.swift.o
ld: symbol(s) not found for architecture x86_64

Notes:

The problem does not occur if the project is compiled in debug mode.
