In the future, Android releases will support DWARF 5, but we need to
ensure that older targets only have DWARF 4 generated for them. This
patch inserts that verification for all Android releases now. The patch
also fixes 2 minor mistakes (a mistakenly moved RUN line, and the
missing G_DWARF2 check label).
