buildgcc: Fix the options check

1. Add -P|--package to build iasl
    2. Remove -G|--skip-gdb, which was to skip gdb.
    3. Add -S|--scripting to build gdb
    4. Remove -C|--clang, which was to build clang.

All these changes are aligned with the options parsing below.
    The help text is correct.
