This fails to compile on OSX and the BSDs:
/Users/pm215/src/qemu-for-merges/util/memfd.c:208:19: error: implicit
declaration of function 'memfd_create' is invalid in C99
[-Werror,-Wimplicit-function-declaration]
        int mfd = memfd_create("test", 0);
                  ^


I also got
TEST: tests/boot-serial-test... (pid=15159)
  /sparc64/boot-serial/sun4u:                                          **
ERROR:/home/petmay01/linaro/qemu-for-merges/tests/boot-serial-test.c:139:check_guest_output:
assertion failed: (output_ok)
FAIL

on an x86-64/linux host, but I have a feeling that's one of
our intermittents rather than anything in this patch.

thanks

Will fix like this in v2:
