What does the -N flag do?
Looking at the manpage for v2.26.1:
-N
--omagic
Set the text and data sections to be readable and writable. Also,
do not page-align the data segment, and disable linking against
shared libraries. If the output format supports Unix style magic
numbers, mark the output as "OMAGIC". Note: Although a writable
text section is allowed for PE-COFF targets, it does not conform to
the format specification published by Microsoft.
So, today we don't try and use a writable text section anywhere, perhaps
we can do -N --no-omgic (which negates most of what -N does, but since
we use a custom linker script I think at least the alignment part above
isn't true anyhow) ?
