This improves #12440. The previous change was a bit fragile if we updated
commander versions. This change now implements a better solution that
doesn't rely on dependencies and their locations for detecting if we need
to run the `configure` action for hextobin.
This change fixes a dependency problem when building Core. Previously
this failed on a clean source tree because hextobin was missing
dependencies but didn't run its `configure` action if the top-level
`node_modules` folder did already exist.
Note: there is a bit of potential confusion about the difference between
/resources/builder.inc.sh (the full implementation for builder scripts),
and /resources/build/builder.inc.sh (the source script that builder
scripts should always use).
This allows us to make assumptions that will always be true for builder
scripts that may not be true for other scripts, such as setting base
folder.
Fixes#11324.
* Always `cd "$THIS_SCRIPT_PATH"`
* Remove unnecessary `cd` from all build.sh
* Remove unnecessary `set -eu` from all build.sh (and `# set -x`)
* Replace old build-utils.sh incantation in a few build.sh scripts
