+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
+
+Actually if we make it like this:
+
+#include <stdio.h>
+#include <sys/auxv.h>
+
+int main(int ac, char **av)
+{
+    for (int i = 0; i < 32; ++i)
+        if ((int)(getauxval(AT_HWCAP2) & (1 << i)))
+            printf("%d\n", i);
+}
+
+
+clang mytest.c -target aarch64-linux-gnu -fsanitize=memtag -march=armv8+memtag
+qemu-aarch64 --cpu max -L /usr/aarch64-linux-gnu ./a.out
+
+I see only: HWCAP_FP HWCAP_CRC32 HWCAP_ATOMICS
+So no HWCAP2_BTI as well.
+
+Sorry, 0 7 8 should be "HWCAP2_DCPODP HWCAP2_FLAGM2 HWCAP2_FRINT"
+
+Yep, there's a whole bunch that have been missed.

+
+This has missed 6.0, but should be acceptable to roll into 6.0.1.
+
+Thanks for the quick fix!
