Hadrian fails to run test cases

Summary

Compiling utils/check-exact/Preprocess.hs fails with unknown symbol 'allocateWrite'.

Steps to reproduce

On a fresh extracted tree (in my case 20210402) run:

hadrian/build clean
hadrian/build --flavour=devel2 -j2 -c

hadrian/build test --flavour=devel2 --freeze1 -j2 --only=break012 stage2:exe:ghc-bin

The first 2 commands work well. However the third fails before running the test case:

The issue doesn't occur on an older tree with newest commit c83e4d05.

Expected behavior

Hadrian should build all necessary programs and run the test case.

Environment

• GHC version used: 8.10.2 and 9.0.1
