gnu: racket: suppress build stamp 
The `build-stamp` configuration key should generally be set to an empty
string for a release build. The automatically inferred build stamp is
especially unhelpful with Guix, since it ends up being the Unix epoch.

* gnu/packages/racket.scm (racket-minimal)[arguments]: Adjust the
'initialize-config.rktd phase to set 'build-stamp to "".

;; Commentary:
;;
;; Here's how bootstrapping minimal Racket works:
;;
;; - Racket BC [CGC] can be built with only a C compiler (except for
;; one caveat discussed below).
;; - Racket BC [3M] needs an existing Racket to run "xform",
;; which transforms its own C source code to add additional annotations
;; for the precise garbage collector.
;; - Racket CS needs (bootfiles for) Racket's fork of Chez Scheme.
;; It also needs an existing Racket to compile Racket-implemented
;; parts of the runtime system to R6RS libraries.
;; - Chez Scheme also needs bootfiles for itself, but Racket can simulate
;; enough of Chez Scheme to load Racket's fork of the Chez Scheme compiler
;; purely from source into Racket and apply the compiler to itself,
;; producing the needed bootfiles (albeit very slowly).
;; Any variant of Racket since version 7.1 can run the simulation.
;;
;; So, we build CGC to build 3M to build bootfiles and CS.
;;
;; One remaining bootstrapping limitation is that Racket's reader, module
;; system, and macro expander are implemented in Racket. For Racket CS,
;; they are compiled to R6RS libraries as discussed above. This note from the
;; README file applies to all such subsystems:
;;
;; The Racket version must be practically the same as the current Racket
;; verson, although it can be the Racket BC implementation (instead of
;; the Racket CS implementation).
;;
;; Unlike Chez Scheme boot files, the files generated in "schemified"
;; are human-readable and -editable Scheme code. That provides a way
;; out of bootstrapping black holes, even without BC.
;;
;; However, other Racket subsystems implemented in Racket for Racket CS
;; use older C implementations for Racket BC, whereas the reader, expander,
;; and module system were completely replaced with the Racket implementation
;; as of Racket 7.0.
;;
;; For Racket BC, the compiled "linklet" s-expressions (primitive modules)
;; are embeded in C as a static string constant. Eventually, they are further
;; compiled by the C-implemented Racket BC bytecode and JIT compilers.
;; (On platforms where Racket BC's JIT is not supported, yet another compiler
;; instead compiles the linklets to C code, but this is not a bootstrapping
;; issue.)
