Currently, there are a number of compiler warnings generated when
building the addons on Linux, for example:

  CXX(target) Release/obj.target/binding/binding.o
  SOLINK_MODULE(target) Release/obj.target/binding.node

This commit adds the flag -Wno-cast-function-type to suppress these
warnings. With this change the warnings are not displayed anymore and
the output matches that of osx when running
'make -j8 test/addons/.buildstamp'.

Currently, the make-callback-domain-warning addon generates the
following warning:

This commit fixes this warning.

Users of MakeCallback that adds the domain property to carry context,
should start using the async_context variant of MakeCallback or the
AsyncResource class.
