    ELF: Properly group and place orphan note sections

    Properly group orphan note sections.  When placing orphan note section
    as the first note section, place it after the section before all note
    sections.

ld properly groups and places orphan note sections.  If .note.gnu.build-id
is added to elf.sc, the orphan .note.gnu.property section will be placed
before the .note.gnu.build-id section due to the larger section alignment
and may be placed in the same PT_LOAD segment with text sections.  Remove
.note.gnu.build-id from elf.sc to let ld properly group and add all orphan
note sections.

Binutils 2.44 has been fixed by a different fix:

commit 052940eba6
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Fri Sep 20 11:32:26 2024 +0800

    ld: Ignore .note.gnu.build-id when placing orphaned notes
