NAKAMURA Takumi 7c771b0293 Revert r220174, "Always use -Wl,-gc-sections on our build."
It dropped required functions for plugins with gnu ld 2.20 and 2.21.

      LLVM :: Feature/load_module.ll

      Clang :: Frontend/plugins.c

  error: unable to load plugin 'lib/PrintFunctionNames.so': 'lib/PrintFunctionNames.so: undefined symbol: _ZN5clang15PluginASTAction6anchorEv'

I think we should inspect linker's version or behavior to introduce --gc-sections for --export-dynamic.
