Here is completely untested patch that implements something,

But it tries to have the native/swap/big/little choice orthogonal from
native/r16_ieee/r16_ibm with r16_ieee and r16_ibm only supported on
ppc64le-linux.
For INQUIRE it has the so far perhaps manageable set of possibilities
handled so that it uses string literals and doesn't have to construct
those strings at runtime (haven't studied how it would need to be done).
I'm afraid I don't know that stuff enough to move forward from this.
That looks like the direction to go.
I will take it from there and see if I can find some hours over the
weekend to work on something. Unfortunately, my daytime job will
kick in again on Monday :-)
One thing that one has to watch out for is a big-endian IBM long double
file, so the byte swapping will have to be done before assigning
the value.
