The -O flag is currently being mostly ignored; it's only checked whether or not the output format is "binary". This adds support for a few formats (e.g. elf64-x86-64), so that when specified, the output can change between 32/64 bit and sizes/alignments are updated accordingly.

As a side effect, this also fixes a bad alignment in symbol table when the input format is "binary".

This fixes PR39135
