+qemu --static user build fails with fedora rawhide glibc-2.30.9000
+
+Building qemu latest git 654efcb511d on fedora rawhide fails with this configure line:
+
+./configure \
+	--static \
+	--disable-system \
+	--enable-linux-user \
+	--disable-werror \
+	--disable-tools \
+	--disable-capstone
+
+make fails with:
+
+/usr/bin/ld: linux-user/syscall.o: in function `do_syscall1':
+/root/qemu.git/linux-user/syscall.c:7769: undefined reference to `stime'
+collect2: error: ld returned 1 exit status
+
+Seems related to this glibc change: https://sourceware.org/git/?p=glibc.git;a=commit;h=12cbde1dae6fa4a9a792b64564c7e0debf7544cc
+
+...
+
++* The obsolete function stime is no longer available to newly linked
++  binaries and it has been removed from <time.h> header.  This function
++  has been deprecated in favor of clock_settime.
++
+
+# rpm -q glibc
+glibc-2.30.9000-17.fc32.x86_64
+
+
+FWIW there's some other messages but I don't think they are fatal:
+
+/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/9/../../../../lib64/libglib-2.0.a(gutils.c.o): in function `g_get_user_database_entry':
+(.text+0x267): warning: Using 'getpwuid' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
+/usr/bin/ld: (.text+0xe0): warning: Using 'getpwnam_r' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
+/usr/bin/ld: (.text+0x11e): warning: Using 'getpwuid_r' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
+
+
+Also, --disable-capstone is required to avoid this error, but it is pre-existing, not sure if it's a bug, if so I can file a separate one:
+
+  LINK    aarch64-linux-user/qemu-aarch64
+/usr/bin/ld: cannot find -lcapstone
+collect2: error: ld returned 1 exit status
+
+We use stime() to implement the target stime syscall. We should probably switch to using clock_settime(CLOCK_REALTIME, ...) instead, as that's what glibc uses internally now to implement its stime():
+
+https://sourceware.org/git/?p=glibc.git;a=blob;f=time/stime.c;h=6ea3b6dcc1a393b57b69ca24fbfe8023d9095837;hb=12cbde1dae6fa4a9a792b64564c7e0debf7544cc
+
+
+Fixed by 0f1f2d4596ae ("linux-user: remove host stime() syscall")
