Julia requires more than 4GB – currently the 8GB of my laptop are full
and extended by 6GB of swap; still building and maybe will fail — and
supports these platform:

                    x86-64         (64-bit)  
                    i686           (32-bit)          
                    ARMv8          (64-bit)          
                    ARMv7          (32-bit)          
                    PowerPC        (64-bit)  
    CUDA 10.1       Nvidia CUDA    (64-bit)
    ROCM            AMD ROCM       (64-bit)  
    oneAPI          Intel oneAPI   (64-bit)

Upstream provides binaries for these.  AFAIK, for most of them, Julia is
cross-compiled and not natively compiled.  Well, I am still missing the
point to natively compile on limited boards.

Having substitutes running on non-x86_64 architectures is one thing,
directly build on these non-x86_64 architectures is another.

(I am not saying that direct builds on these non-x86_64 architectures is
not interesting by itself but that I miss the aim of such for some heavy
packages as Julia or GHC or else.)
