Add libjulia 1.3.1

There is no libLLVM_jll 6.0.1 which complicates this, I guess...

[fingolfin]

I might try using LLVM_jll.jl 6.0.1

[fingolfin]

Looking pretty good!

Anybody got an idea what this might be about (from here):

 /opt/powerpc64le-linux-gnu/bin/../powerpc64le-linux-gnu/sys-root/usr/local/lib/libLLVM-6.0.so: undefined reference to `__tls_get_addr_opt@GLIBC_2.22'

Something like ldc-developers/druntime@2f05aa1

might work. @vchuravy better ideas?

We use Glibc 2.17 for PPC , this looks like LLVM at that point was build against 2.22. So likely we need to rebuild LLVM 6.

[giordano]

That's a much more sensible observation 😅

[fingolfin]

Ok. I guess one could also try to create a libLLVM 6.0.1 instead? Not sure how much extra work that'd take, though?

[vchuravy]

You can also skip PPC support for 1.3

[fingolfin]

I will skip the PowerPC builds then (although it's a bit of a pity, as it complicates the work on packages like libcxxwrap-julia if one wants to support as many platforms as possible: one has to very carefully match the platform selection in the various libjulia_jll variants.

[fingolfin]

Can this be merged now? While I hope that perhaps we can eventually add back the powerpc support, this is stalled for the moment (see PR #1914), so it'd be nice to not hold this up for the sake of a fringe (no offense intended) platform. Unless you think it'll be "easy" to resolve the LLVM 6.0.1 build issue on macOS?
