Title:
  Access to /proc/self/exe in linux-user mode

Status in QEMU:
  New

Bug description:
  This is based on a recent bug in GCC Bugzilla:
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60681

  It looks like libbacktrace (GCC runtime library used for obtaining
  stack traces) uses /proc/self/exe for error reporting. Currently this
  is mapped to qemu-arm which effectively disables libbacktrace on
  linux-user.

  It seems that QEMU already supports /proc/self/{maps,stat,auxv} so
  addition of /proc/self/exe may be trivial.
