Is this change for working around core / modules issue?

[ikilpatrick, 2015/12/22 23:40:23]

Yup, this is to get the component builds working.
../../third_party/WebKit/Source/bindings/core/v8/V8DOMWrapper.h:94: error:
undefined reference to
'blink::V8DOMWrapper::hasInternalFieldsSet(v8::Local<v8::Value>)'

As WorkletScriptController (in modules) is importing V8DOMWrapper.h the inline
functions V8DOMWrapper::associateObjectWithWrapper, etc need this exported to
link.
