[Pkg-julia-devel] Bug#861484: Bug#861484: Bug#861484: Bug#861484: Bug#861484: julia: FTBFS on arm64

[Graham Inggs]

Julia builds successfully on a Raspberry Pi 3 running an image
prepared by xylnao, dated 2016-04-14 [1] with kernel 4.5.0.
It fails in the same way as on arm-arm-04 and arm-conova-01 on a
Raspberry Pi 3 running an image prepared by Michael Stapelberg, dated
2017-03-22 [2] with kernel 4.9.18-1.
Both images were upgraded to current Stretch and 1GB was allocated for
a swapfile.

The build failures occur after the Julia executable has been built,
when it is run for the first time in order to compile coreimg.jl.

Instead of building the package, the segfault should be reproducible
by installing julia from the archive and then running 'julia' from a
terminal.

You should get output similar to:

...but this is bad:
