Hex.pm package for 0.2.4 is broken on non-OSX

[martin-langhoff]

The package in Hex.pm includes OSX (Mach-O) objectfiles. These files break the build on any non-OSX platform. On Linux, I see

===> Hook for compile failed!

** (Mix) Could not compile dependency :lz4, "/home/vagrant/.mix/rebar3 bare compile --paths "/vagrant/_build/dev/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile lz4", update it with "mix deps.update lz4" or clean it with "mix deps.clean lz4"


$ file /vagrant/deps/lz4/c_src/lz4.o
/vagrant/deps/lz4/c_src/lz4.o: Mach-O 64-bit object

Grabbing lz4 from github works well.
