* Get rid of the RCS Header stuff.  They're meaningless in git.
 * Add public domain comment to some of the files if the only comment
   was the RCS header.

having the address of builtin_image_flag set to some (random) address
of mapped memory that is non-zero, we add a special file to lisp.a
that defines builtin_image_flag to 1.

lisp/Config.sparc_common:
o Define EXEC_FINAL_OBJ

lisp/GNUmakefile:
o Make lisp.a depend on EXEC_FINAL_OBJ
o On Solaris, add EXEC_FINAL_OBJ to lisp.a.

tools/SunOS-cmucl-linker-script:
o Remove the line setting the address of builtin_image_flag.

tools/linker.sh:
o For Solaris, we don't need to define BIFLAG; the builtin_image_flag
  is automatically set correctly by linking in lisp.a
