Thank you, the error no longer occurs after adding -mno-outline-atomics or -march=armv8.1-a
I installed packages on debian-12 (arm64) from https://apt.postgresql.org/pub/repos/apt, the error is repeated.

Hmm, I think it is inlining spinlock code from
pg_last_wal_receive_lsn()'s call to GetWalRcvFlushRecPtr(), and then
failing to find fallbacks for pre-ARMv8.1 systems that didn't have the
LSE atomic instructions. I wonder if there could be some mismatch in
the default -march for parts of your toolchain, so that it doesn't
link the library that has that stuff, but then the clang that built
walreceiverfuncs.bc expects it to be found. I wonder if it goes away
if you add "-mno-outline-atomics" or "-march=armv8.1-a" or
"-march=armv8-a+lse" to BITCODE_CXXFLAGS (not saying that's a fix,
just trying to understand what's happening...). Assuming you're using
GCC, maybe "gcc -Q --help=target | grep march" could show what Ubuntu
24 has set as the baseline, and "clang -### -c -x c /dev/null" might
show what clang is selecting... just ideas, I'm not sure, I don't have
such a system, I just noticed a few distros cranking up the baseline
instruction sets recently...
