Remove contrib/build_sysimg.jl

[staticfloat]

Users should instead use PackageCompiler.jl as it is more fully-featured and better maintained.

A separate topic - we should bring PackageCompiler in here or at least make it part of the default Julia distribution. It could use more CI and testing.

+1 to PackageCompiler in stdlib.

Since you're deleting the file, could you similarly remove the section in the documentation that recommends using it? https://docs.julialang.org/en/v1/devdocs/sysimg/#Building-the-Julia-system-image-1

[ararslan]

This seems to have broken make binary-dist. See this buildbot build: https://build.julialang.org/#/builders/53/builds/412

Can we revive a discussion of bringing PackageCompiler functionality to stdlib please?

What would it take to make such a PR?

edit:
Or at least part of the default Julia distribution, as suggested by @ViralBShah above. The package is undermaintained and undertested. @SimonDanisch said it needs a lot of cleanup that will take time but is not too difficult. Perhaps it's feasible for JSOC (someone can DM me on slack if money is the bottleneck for new JSOCs).

[ViralBShah]

For a JSOC, we need an identified competent student and money. Do we have someone in mind for this?

[chriscoey]

Not on my end. Perhaps there were some capable people whose ideas were turned down for JSOC?
