xcompile: Use local variables and make cosmetic changes

Declaring function variables local improves bash scripts' robustness.

Cosmetic changes among other things include renaming variables from
    plural to singular and vice versa as appropriate, and replacing spaces
    with tabs.

Tested by confirming that sorted output generated by
    util/xcompile/xcompile is the same before and after the change.
