The first commit is just noise, so you can skip it.
The second commit is clear, where was a missing check for mintelf so that was the reason why it was failing only for mint.
The third commit is basically an adjusted copy&paste from include/mint/Makefile.am since that one's make install works and include/Makefile.am's make install doesn't.
This is my attempt to fix #2.
