==============

+ Heap emulation is disabled when a "suspicious" call to brk(2) is
  actually legit, as it might be the case when launching the very
  first program.

+ The "-0" and "-S" options ("root" identity emulation) now fake
  success of mknodat(2), as it was the case for mknod(2) previously.
  This missing feature was revealed by the AArch64 port.

+ The "-k" option (kernel compatibility emulation) now works on
  Linux/AArch64.

Thanks to Rémi Duraffort for the bug reports and for his LAVA testing
platform!
