[Ipopt] API to Determine if Linear Backend is Present?

[Breannan Smith]

Is there functionality within the Ipopt API to determine whether or
not a given linear backend is available? I suppose I can instantiate a
dummy problem with the desired solver and check the return value, but
I wanted to see whether or not something simpler is available.

Thanks!
