proc: add support for last_processor
Read last_processor (new member) from thread_info structures, and fill stat
structure with this.
* configure.ac: Check whether thread_sched_info structure includes
`last_processor' member.
* proc/info.c (S_proc_getprocinfo)
[HAVE_STRUCT_THREAD_SCHED_INFO_LAST_PROCESSOR]: Set `last_processor' field.
* procfs/process.c (process_file_gc_stat)
[HAVE_STRUCT_THREAD_SCHED_INFO_LAST_PROCESSOR]: Set last processor proc
field to `thsi->last_processor'.
[!HAVE_STRUCT_THREAD_SCHED_INFO_LAST_PROCESSOR]: Set last processor proc
field to 0.
