Merge remote-tracking branch 'riku/linux-user-for-upstream' into staging 

# By Erik de Castro Lopo (2) and others
# Via Riku Voipio
* riku/linux-user-for-upstream:
  linux-user: pass correct parameter to do_shmctl()
  linux-user: create target_structs header to place ipc_perm and shmid_ds
  flatload: fix non-GOT relocations
  linux-user: Implement handling of 5 POSIX timer syscalls.
  linux-user: Add target struct defs needed for POSIX timer syscalls.
