[PATCH libevdev 2/2] test: add basic link test

[Peter Hutterer]

This test doesn't do anything but compile and link against libevdev. It's a
simple protection to avoid linker errors. If we ever have libs we depend on
and they don't get resolved properly, this test should warn us in time.

This happened in a different library - it was missing the ldflags and thus
all users had unresolved symbols if they didn't link to the same libraries
explicitly. Doesn't happen here but better safe than sorry.
