Re: gnu: julia: Fix test suite regression.

[Andreas Enge]

Hello Simon,

you wrote recently that Julia requires more than 4GB to build, and the 16GB
of my laptop were indeed not enough. Now I see this on CI for i686:
Error in testset core:
Error During Test at 
/tmp/guix-build-julia-1.8.3.drv-0/julia-1.8.3/test/testdefs.jl:21
  Got exception outside of a @test
  LoadError: OutOfMemoryError()

Can we deduce that Julia is no more (?) able to be built on 32 bit systems?
Should we remove those from the supported systems?

Andreas
