        <pre>When not using a linker script with SECTIONS we should probably round the size
of executable PT_LOAD to a page size and pad it with traps.

The reasoning is that if we don't do it any tool editing the file can remove
the traps.

Currently even lld will put non SHF_ALLOC bits if the executable PT_LOAD is at
the end.

There was an old attempt at it in D33630. We can hopefully make it simpler now.</pre>
