mkl: Add a small test program

The MKL pkg-config files often change and are then incorrect for our
paths. pkg-config validation finds some issues, but not incorrect
paths. So, add a small test program to test whether the generated
pkg-config files can actually be used to build a functioning
binary. Hopefully this catches future regressions.
