can you tell me the binutils version used?

building fails with recent binutils master:

builddir/libc.a(dl-reloc-static-pie.o): In function `elf_get_dynamic_info':
srcdir/elf/get-dynamic-info.h:73:(.text+0x4c): relocation truncated to fit: R_AARCH64_ADR_PREL_PG_HI21 against
symbol `_dl_main_map' defined in .data.rel.local section in builddir/libc.a(dl-support.o)
srcdir/elf/get-dynamic-info.h:70:(.text+0x50): relocation truncated to fit: R_AARCH64_ADR_PREL_PG_HI21 against
symbol `_dl_main_map' defined in .data.rel.local section in builddir/libc.a(dl-support.o)

and

$ objdump -t builddir/elf/dl-support.o
...
0000000000000000 g     O .data.rel.local	0000000000000468 .hidden _dl_main_map
...
$ objdump -r builddir/elf/dl-reloc-static-pie.o
...
000000000000004c R_AARCH64_ADR_PREL_PG_HI21  _dl_main_map+0x000000037ffffa40
0000000000000050 R_AARCH64_ADR_PREL_PG_HI21  _dl_main_map+0x000000037ffff1e0
...

those offsets look wrong, i'll need to investigate
