Looks close. The only problem I see is with

Suppose . is not as aligned as the contents of .preinit_array
etc? Then __preinit_array_start will have the wrong value.
I think you want
.preinit_array ${RELOCATING-0} : ${RELOCATING+ALIGN(${ALIGNMENT})} {
${RELOCATING+${CREATE_SHLIB-PROVIDE (__preinit_array_start = .);}}
*(.preinit_array)
${RELOCATING+${CREATE_SHLIB-PROVIDE (__preinit_array_end = .);}}
}
That will make sure you get 4 byte alignment for ELF32 and 8 byte
alignment for ELF64. And assuming that the sections are similarly
aligned, this should work fine.
