Revert "scripts: Various shell script cleanups (#4008)"

This reverts commit fba4fd5314.

The series of commits I made for PR #4008 were squashed into a single
commit and rebased. Somewhere along the way a mistake was made in a
merge conflict resolution, resulting in some bad code in
`bin/buildForWindows.sh`. This commit reverts the bad squashed commit.
