--semaphore is not compatible with build-type: Custom #9197
Description
Describe the bug
Cabal HEAD fails to build any package with build-type: Custom when -j --semaphore is passed.
To Reproduce
Steps to reproduce the behavior:
$ cabal unpack ghc-paths-0.1.0.12 && cd ghc-paths-0.1.0.12 && cabal build -w ghc-9.8.0.20230809 -j --semaphore --allow-newer
Resolving dependencies...
Build profile: -w ghc-9.8.0.20230809 -O1
In order, the following will be built (use -v for more details):
- ghc-paths-0.1.0.12 (lib:ghc-paths) (first run)
Created semaphore called cabal_semaphore_3 with 8 slots.

Expected behavior
The build should complete successfully. If I remove -j --semaphore, all works well.
