GHC master fails to build because of 5bd8ed53

I'm unable to build GHC master on macOS aarch64 because of 5bd8ed53. Reverting it makes compilation succeed.

It fails with:

ghc: panic! (the 'impossible' happened)
  GHC version 9.11.20240325:
    patchJumpInstr: BL
  CallStack (from HasCallStack):
    panic, called at compiler/GHC/CmmToAsm/AArch64/Instr.hs:332:14 in ghc-9.11-inplace:GHC.CmmToAsm.AArch64.Instr
