Adapt to minor API change for 9.6.4 compatibility

[wz1000]

The CPP will need to be adjusted again for 9.8.2 as the patch
is likely to be backported there as well.

[benz0li]

Please adjust again for GHC 9.8.2 as building of HLS 2.6.0.0 currently fails:

• Aarch64: https://gitlab.b-data.ch/ghc/ghc-musl/-/jobs/96363
• x86_64: https://gitlab.b-data.ch/ghc/ghc-musl/-/jobs/96362
