QEMU-user doesn't report HWCAP2_MTE

Reproducible on ffa090bc56e73e287a63261e70ac02c0970be61a

Host Debian 5.10.24 x86_64 GNU

Configured with "configure --disable-system --enable-linux-user --static"

This one works and prints "OK" as expected:
clang tests/tcg/aarch64/mte-3.c -target aarch64-linux-gnu  -fsanitize=memtag -march=armv8+memtag
qemu-aarch64 --cpu max -L /usr/aarch64-linux-gnu ./a.out && echo OK


This one fails and print "0":
cat mytest.c
#include <stdio.h>
#include <sys/auxv.h>

#ifndef HWCAP2_MTE
#define HWCAP2_MTE (1 << 18)
#endif

int main(int ac, char **av)
{
    printf("%d\n", (int)(getauxval(AT_HWCAP2) & HWCAP2_MTE));
}


clang mytest.c -target aarch64-linux-gnu  -fsanitize=memtag -march=armv8+memtag
qemu-aarch64 --cpu max -L /usr/aarch64-linux-gnu ./a.out
