Documentation says BYE is the LISP package, but it appears to be in the SYSTEM package

[Robert Dodier]

Working with GCL 2.6.14 on Linux (Ubuntu). I have built GCL via

  $ ./configure --enable-ansi
  $ make

from gcl-2.6.14.tar.gz obtained from https://mirror.team-cymru.com/gnu/gcl/.

The documentation (info/internal.texi) says that BYE is in the LISP
package, but BYE appears to be in the SYSTEM package instead.

>(find-symbol "BYE" (find-package "LISP"))
NIL
NIL

>(find-symbol "BYE" (find-package "SYSTEM"))
BYE
:EXTERNAL

>(describe 'bye)
BYE - external symbol in SYSTEM package

Dunno what's going on here, whether the documentation needs to be
fixed or the implementation or what.
