Cannot set SB-EXT:*EVALUATOR-MODE* to :INTERPRET when using the sb-fasteval interpreter

[Jeronimo Pellegrini]

After compiling SBCL with

sh make.sh --dynamic-space-size=16Gb --with-sb-fast-eval --without-sb-eval

I tried to set SB-EXT:*EVALUATOR-MODE* to :INTERPRET.

* SB-EXT:*EVALUATOR-MODE*
:COMPILE
* (setf SB-EXT:*EVALUATOR-MODE* :INTERPRET)
; in: SETF *EVALUATOR-MODE*
; (SETF *EVALUATOR-MODE* :INTERPRET)
; --> SETQ
; ==>
; (THE (MEMBER :COMPILE) :INTERPRET)
;
; caught WARNING:
; Constant :INTERPRET conflicts with its asserted type (MEMBER :COMPILE).
; See also:
; The SBCL Manual, Node "Handling of Types"
;
; compilation unit finished
; caught 1 WARNING condition

debugger invoked on a SIMPLE-TYPE-ERROR in thread
#<THREAD "main thread" RUNNING {10008A0083}>:
  Value of :INTERPRET in
  (THE (MEMBER :COMPILE) :INTERPRET)
  is
    :INTERPRET,
  not a
    (MEMBER :COMPILE).

Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [ABORT] Exit debugger, returning to top level.

(SB-C::%COMPILE-TIME-TYPE-ERROR (:INTERPRET) (MEMBER :COMPILE) #<unused argument> (:INTERPRET) "(THE (MEMBER :COMPILE) :INTERPRET)" NIL)
0]

But src/interpreter/README tells me that

" As with sb-eval, the SB-EXT:*EVALUATOR-MODE* variable can be
  set to :INTERPRET or :COMPILE."

I'm not sure what went wrong, but the generated SBCL code doesn't seem to behave
according to what is documented (it requires (member :compile) when using the fast
evaluator?)

That's because it's spelled sb-fasteval.
