* Placing 'G' before 'M' (SHF_MERGE) can be misleading as the sh_entsize argument goes before the section group name, if a reader doesn't know that the order of extra arguments is not affected by the order of flags. * 'a', 'w', and 'x' indicate basic permission-related flags. Separating them with 'G' is kinda ugly. Simplify code and move 'G' after 'o'. The new output is more similar to GCC.
