macOS: Freshly installed GHC 8.10.5 linker reports undefined symbol `___darwin_check_fd_set_overflow`
Just downloaded https://downloads.haskell.org/~ghc/8.10.5/ghc-8.10.5-x86_64-apple-darwin.tar.xz and installed it via ./configure && make install. It does not seem to want to build executables:
$ cabal install alex

cabal: Failed to build exe:alex from alex-3.2.6.I didn't have this problem before, neither with 8.10.4 or 9.0.1. This issue seems to be the same as closed issue #18760 (closed).
Shouldn't ./configure check that I have a compatible infrastructure?
