set default goal since bingo disrupts it

[grokspawn]

Description of the change:
set a default goal of all for the Makefile

Motivation for the change:
since 7a1b8ec the all goal is no longer the first (and therefore default-by-default) goal. This explicitly makes it the default target again.

Reviewer Checklist

• Implementation matches the proposed design, or proposal is updated to match implementation
• Sufficient unit test coverage
• Sufficient end-to-end test coverage
• Docs updated or added to /docs
• Commit messages sensible and descriptive
