-N option coalesce all sections into single LOAD segment which causes
data and other sections to have executable permission causing warning
with new binutils ld 2.39.
New ld emits warning when any segment have all three permissions RWX.
ld.bfd: warning: test.elf has a LOAD segment with RWX permissions
ld.bfd: warning: fw_dynamic.elf has a LOAD segment with RWX permissions
ld.bfd: warning: fw_jump.elf has a LOAD segment with RWX permissions
ld.bfd: warning: fw_payload.elf has a LOAD segment with RWX permissions
This option was added in below commit -
commit: eeab92f2423e ("Makefile: Convert to a more standard format")
Removing -N option allows to have text and rodata into one LOAD
segment and other sections into separate LOAD segment which prevents
RWX permissions on single LOAD segment. Here X == E
