Currently, there are a number of compiler warnings generated when
building the addons on Linux, for example:
make[1]: Entering directory '/node/test/addons/zlib-binding/build'
CXX(target) Release/obj.target/binding/binding.o
SOLINK_MODULE(target) Release/obj.target/binding.node
COPY Release/binding.node
make[1]: Leaving directory '/node/test/addons/zlib-binding/build'
In file included from ../binding.cc:1:

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'.

mainly to allow native addons to export single functions on
rather than being restricted to operating on an existing
object.
Init functions now receive exports as the first argument, like
before, but also the module object as the second argument, if they
support it.
