`build-cabal` target broken with devel2 flavour

From #23490 (comment 514289) :

• I tried running hadrian/build build-cabal at 9c8fdda3 and get seemingly-unrelated errors after a lot of building, which look like this:

  src/Utils/Containers/Internal/TypeError.hs:11:1: error: [GHC-47808]
      Failed to load dynamic interface file for GHC.TypeLits:
        Exception when reading interface file  /path/to/tree/_build/stage1/lib/../lib/x86_64-linux-ghc-9.9.20230719/base-4.18.0.0-inplace/GHC/TypeLits.dyn_hi
          /path/to/tree/_build/stage1/lib/../lib/x86_64-linux-ghc-9.9.20230719/base-4.18.0.0-inplace/GHC/TypeLits.dyn_hi: withBinaryFile: does not exist (No such file or directory)
     |
  11 | import GHC.TypeLits
     | ^^^^^^^^^^^^^^^^^^^

  This looks a bug in hadrian. (I've selected devel2 as my default flavour.) If the *.dyn_hi files will be needed later, either they should get built or hadrian should complain immediately without building intermediate junk for 90 minutes first.
