Binary Files weirdness

[lawinslow]

We know R doesn't like binary files in a package, but according to the documentation, a file called "BinaryFiles" can be added to the package. Despite having that file in our package, we continue to get this warning

• checking for .dll and .exe files ... WARNING
  Found the following executable files:
  inst/extbin/win32GLM/glm.exe
  inst/extbin/win32GLM/hdf5_hldll.dll

  inst/extbin/winGLM/szip.dll
  inst/extbin/winGLM/zlib1.dll
  Source packages should not contain undeclared executable files.

And of course, more confusingly,

Non-standard file/directory found at top level:
'BinaryFiles'

I get this on both R v3.3.2 and bleeding edge R-devel version.

To get travis running, I'm just telling it to ignore warnings for now.
