linker_unload_native is fragile on dynamic alpine builds on 9.6
linker_unload_native
is supposed to pass on dynamically linked alpine: e75a58d1
However, it seems to be fragile on the 9.6 branch.
Unexpected pass: https://gitlab.haskell.org/ghc/ghc/-/jobs/1670261
Unexpected fail: https://gitlab.haskell.org/ghc/ghc/-/jobs/1671878
I'm marking it as fragile for all platforms on 9.6 because we don't have a way to mark a test as fragile only on a particular platform.
