bug#47354: (build-system julia) not reproducible

[zimoun]

Hi,

Working on Julia packages, see [1], I note that the Julia build system
is not reproducible.  It is probably linked to this issue:

   <http://issues.guix.gnu.org/issue/22304>


Concretely, let pick the package ’julia-adapt’:

--8<---------------cut here---------------start------------->8---
$ diff -r --no-dereference 
/gnu/store/3rvnp4q49k32yrv9iaxpyj2xpk8x3bi7-julia-adapt-3.1.1{,-check}
Binary files 
/gnu/store/3rvnp4q49k32yrv9iaxpyj2xpk8x3bi7-julia-adapt-3.1.1/share/julia/compiled/v1.5/Adapt/rUIgN_JghfZ.ji
 and 
/gnu/store/3rvnp4q49k32yrv9iaxpyj2xpk8x3bi7-julia-adapt-3.1.1-check/share/julia/compiled/v1.5/Adapt/rUIgN_JghfZ.ji
 differ
--8<---------------cut here---------------end--------------->8---

I do not know if it is fixed by upstream with the recent release
julia@1.6.  Probably not.  Any help to remove this unreproducibility is
welcome. :-)

Cheers,
simon
