bug#54929: ./pre-inst-env recompiling files

[Andreas Enge]

Recently even after a
   ./bootstrap
   ./configure --localstatedir=/var --prefix=/usr/local/guix
   make

any command prefixed by ./pre-inst-env starts by recompiling a bunch of
scheme files with the following messages:
;;; WARNING: loading compiled file 
/home/andreas/Programme/guix/guix/build/utils.go failed:
;;; In procedure load-thunk-from-memory: incompatible bytecode version
;;; note: source file /home/andreas/Programme/guix/guix/build/utils.scm
;;;       newer than compiled 
/run/current-system/profile/lib/guile/3.0/site-ccache/guix/build/and so on.

Then it used to fail, but on my last run it succeeded in the end.

However, the next ./pre-inst-env executes the same recompilation dance.
