Like this:

  (gdb) p Fsymbol_value(intern("emacs-bzr-version"))
  $5 = 57020481
  (gdb) xtype
  Lisp_String
  (gdb) xstring
  $6 = (struct Lisp_String *) 0x3661040
  "116894 rudalics@gmx.at-20140402143333-a56l2vy9oak0njsg"

Alas, you cannot do this when debugging a core file, you need a
running program.
