Toolchain: Fix expansion bugs and make BuildIt.sh shellcheck compliant

BuildIt.sh had a bunch of SC2086 errors, where we were not quoting
variables in variable expansions. The logic being:

    Quoting variables prevents word splitting and glob expansion,
    and prevents the script from breaking when input contains spaces,
    line feeds, glob characters and such.

    Reference: https://github.com/koalaman/shellcheck/wiki/SC2086

As bcoles noticed in #6772, shellcheck actually found a real bug here,
where the user's build directory included spaces.

Close: #6772
