  rts: Avoid static symbol references to ghc-internal
  
  This resolves #26166, a bug due to new constraints placed by Apple's
  linker on undefined references.
  
  One source of such references in the RTS is the many symbols referenced
  in ghc-internal. To mitigate #26166, we make these references dynamic,
  as described in Note [RTS/ghc-internal interface].
  
  Fixes #26166

  compiler: Add libc allocator functions to libc_funs
  
  Prototypes for these are now visible from `Prim.h`, resulting in
  multiple-declaration warnings in the unregisterised job.

  rts: Minimize header dependencies of Prim.h
  
  Otherwise we will end up with redundant and incompatible declarations
  resulting in warnings during the unregisterised build.
