Sorry, this is probably the commit that broke things (not the one above). I was added in glibc 2.25:

Title:
  linux-user clone() can't handle glibc posix_spawn() (causes locale-gen
  to assert)

Status in QEMU:
  New

Bug description:
  I'm running a command (locale-gen) inside of an armv7h chroot mounted
  on my x86_64 desktop by putting qemu-arm-static into /usr/bin/ of the
  chroot file system and I get a core dump.

  locale-gen
  Generating locales...
    en_US.UTF-8...localedef: ../sysdeps/unix/sysv/linux/spawni.c:360: __spawnix: Assertion `ec >= 0' failed.
  qemu: uncaught target signal 6 (Aborted) - core dumped
  /usr/bin/locale-gen: line 41:    34 Aborted                 (core dumped) localedef -i $input -c -f $charset -A /usr/share/locale/locale.alias $locale

  I've done this same thing successfully for years, but this breakage
  has appeared some time in the last 3 or so months. Possibly with the
  update to qemu version 2.8.
