bug#25314: clisp not reproducible

[Ricardo Wurmus]

The build of CLISP is not reproducible.  There are three files that
differ:

diff -r /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49 /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49-check/
Binary files /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49/lib/clisp-2.49/base/lisp.a and /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49-check/lib/clisp-2.49/base/lisp.a differ
Binary files /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49/lib/clisp-2.49/base/lispinit.mem and /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49-check/lib/clisp-2.49/base/lispinit.mem differ
Binary files /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49/lib/clisp-2.49/base/lisp.run and /gnu/store/lf2ybanhxpvbgbxcsxmc733v010g15fp-clisp-2.49-check/lib/clisp-2.49/base/lisp.run differ

This also affects packages that use CLISP to build executables.

bug#25314: timestamp

[Ricardo Wurmus]

The file ./src/constobj.d contains this:

--8<---------------cut here---------------start------------->8---
#ifdef __DATE__
  LISPOBJ_S(lisp_implementation_version_built_string,__DATE__ __TIME__)
#else
  LISPOBJ(lisp_implementation_version_built_string,"NIL")
#endif
--8<---------------cut here---------------end--------------->8---

diffoscope indicates that this may be the cause of the irreproducible
build of lib/clisp-2.49/base/lisp.run.

This is now fixed in c26ba570cce88a9c2529df722042648e34181e42, but clisp
is still not reproducible because the initial memory dump (lispinit.mem)
differs.  Diffoscope does not show anything obvious.
