--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
-Ttext 0 is asking to place the .text section at address zero.  Assuming you're
playing with x86_64, the -N script starts laying out the text segment at
0x400000.  So a number of sections are placed there after allowing for headers.
 Then we reset to address zero for .text and place a number of sections there,
and since .bss is so large, its vma overlaps the first section, .note.ABI-tag.

Not a bug, you asked for overlapping sections.

I suspect grub2 should be using -Wl,-Ttext-segment,0.
