Test failures on Alpine Linux

[ararslan]

I'm running Alpine Linux 3.7 in Docker with Julia master built from source, and I'm getting the following test errors:

• Command line arguments

There was also a failure in the Sockets stdlib tests but I think that's due to my setup more than anything else.

@tkelman Have you seen these before?

[guslen]

Hi,
Did you take into account that Alpine Linux is built on musl libc? At the repository of Apache httpd on Docker Hub they also warn you that things can turn out funny because it is not the commonly used GNU libc "glibc" which is used by default in the other Linux projects/distributions.
Here is a Docker image of Alpine with GNU libc.
Maybe it's going to help you, I'm by no means an expert or have any experience compiling Julia, but I compiled other software and this was sometimes a major show stopper. Not for the compilation itself but for running the software later.

[ararslan]

Yes, I'm familiar with Alpine Linux and musl, and it's my understanding that we don't require glibc on Linux. See for example #26358, which fixed source building on Alpine, and the Alpine Julia port, which does not depend on glibc.

I just rebuilt master and ran these tests again. cmdlineargs still fails but precompile now passes. I don't know why, but hey, it works.
