Get build_package_in_chroot target from metadata.default_target.

• The only test I did was to make sure it built.
• It silently reverts to the platform native target if...
  • there was an error getting the metadata.
  • the user gave a target that was unsupported.

Again, sorry if this is an incredibly stupid PR and I'm just missing something.

Hi @quadrupleslap this is great, thanks for the PR!

But there is a problem. By default (without any target in CompileOptions docs.rs' cargo is building documentation into /home/cratesfyi/cratesfyi. But when you provide some target, it will build into /home/cratesfyi/cratesfyi/{TARGET}. Your patch is working for building non-default target but docs.rs is failing to copy default documentation since it's not available in default location.

But this is right approach and I was exactly thinking the same when I first added Metadata. I'll fix it when I find some time, thanks again!

Thank you! I hope you get around to it sometime.

This looks like it got superseded by #255, so i'm going to close this. If you think that this PR should still be considered, feel free to comment and reopen!
