I'm definitely interested in trying to reproduce the problem as it
sounds like there might be a linker bug. Andreas, can you send me
your configure options?

These tricks would only help the particular case of reloc overflow in
branches to __do_global_{c,d}tors_aux. Something like the following
(untested!) in place of the .text output section description in
ld/scripttempl/elf.sc ought to work.
.text ${RELOCATING-0} :
{
${RELOCATING+${TEXT_START_SYMBOLS}}
*crtend.o(.text .stub${RELOCATING+ .text.* .gnu.linkonce.t.*})
*crtend?.o(.text .stub${RELOCATING+ .text.* .gnu.linkonce.t.*})
*(EXCLUDE_FILE (*crtbegin.o *crtbegin?.o) .text .stub${RELOCATING+ .text.*
.gnu.linkonce.t.*})
*crtbegin.o(.text .stub${RELOCATING+ .text.* .gnu.linkonce.t.*})
*crtbegin?.o(.text .stub${RELOCATING+ .text.* .gnu.linkonce.t.*})
/* .gnu.warning sections are handled specially by elf32.em. */
*(.gnu.warning)
${RELOCATING+${OTHER_TEXT_SECTIONS}}
} =${NOP-0}
