  rts: keep checkEnteredTaggable in the linker symbol table
  
  checkEnteredTaggable is public RTS API (rts/include/rts/Messages.h) and
  compiled object code calls it directly, so the RTS linker lists it
  alongside the stg_enteredTaggable stub. Dropping it broke every
  interactive-linking test: GHCi failed to resolve the symbol when
  loading libraries whose constructor entries reference it.
