Parallel checkouts don't work with additionalInstructions defined in compile.yaml

[singhd789]

Describe the bug
When using fre make tools, if components in the compile.yaml includes additionalInstructions, the parallel checkout does not work. This is because as the git clones run in parallel, other steps that want to go into those clones repos, but if they're not fully clones yet, it will exit with error.

To Reproduce
Adding additional instructions such as cd [component] in component information in the compile.yaml will cause this issue.

Expected behavior
Even if additionalInstructions are included in components, we want to be able to do parallel checkouts.
