That's just the way it works, so I suppose you could call it a feature.
DejaGnu doesn't support having different dg-do-what values for different
targets within a test, although it can be done from outside the test in
the .exp file. Tests that try to do that are broken.

I wouldn't rely on that feature, either. We have much better ways in
local test directives to skip and xfail tests for different targets.
