GHC 9.2.5 build fails with "Non optional builder 'alex' is not specified"
I try to build GHC 9.2.5 on Linux OpenSUSE.
This step fails:
ghc-build/ghc-9.2.5$ hadrian/build-stack -j --flavour=quick
| Configure package 'unlit'
| Configure package 'ghc-boot-th'
| Configure package 'ghc-heap'
| Configure package 'hpc'
| Configure package 'genprimopcode'
| Configure package 'hsc2hs'
| Configure package 'binary'
| Configure package 'compareSizes'
| Configure package 'terminfo'
| Configure package 'transformers'
| Configure package 'deriveConstants'
| Configure package 'genapply'
| Configure package 'rts'

After it I tried to do stack install alex
(it was installed successfully), and ran again failing command, but it leaded to the same error. My final goal is to get GHC-9.2.5 without GNU MP dependency, but even flavour=quick fails.
