I don't see this being conditionalised in the Gyp build.  If it builds with
newlib, can we remove this "source -= ..." for simplicity?

Unfortunately not, this breaks under newlib because of missing file path support
from base.

     sources -= [
       "json_file_value_serializer.cc",
       "json_file_value_serializer.h",
