[CRIU] [PATCH 0/3] no more link crtools against the syscall lib

[Laurent Dufour]

This series is removing the need for crtools to be linked with the
builtin syscall library.

This syscall library mimics the syscall part of the C library and is
required by the parasite code which can't rely on the C library.

The crtools binary is linked with the C library and thus don't need
the builtin syscall lib. This should ease the work to split criu in
multiple independent parts as expected in criu 2.

I did tests on the following architectures:
 - x86_64, build and tests are successful
 - ppc64le, build and tests are successful
 - arm, build success but tests are failing as with CRIU 1.8
 - aarch64, build success but tests are failing as with CRIU 1.8

Laurent Dufour (3):
  build: conditional define of struct prctl_mm_map
  namespace: move definition of CLONE_SUBNS
  crtools: no more linked with builtin syscall
