Add ARCH variable to Makefiles
...
In some Makefiles the ARCH variable was not set, although it was used.
In executer/user/Makefile.in it was used before it was set.

Speed up parallel builds
...
- make should be $(MAKE)
- add + in front of rules spawning long-lasted make process in a
subshell. (This would not be needed with $(MAKE) -C .. target, but our
makefiles do not handle that because they use $(PWD))
- split the main 'all' rule as all 4 targets are independant
- fix dependencies where appropriate for parallelism
Extra, not speed-related changes:
- remove some double-colon for targets as they do not need it
This cuts build time from 5s to 1.5s on a laptop with -j4, and more
importantly from 85s to 35s on a KNL node.
As a bonus, the fixed dependencies removes the need to clean before
rebuilding all the time. Probably.

mcexec: Add --stack-premap=<premap_size>[,<max>]

<premap_size> of stack is pre-mapped on creating a process.
And its max size of stack is set to <max>.
This replaces MCKERNEL_RLIMIT_STACK=<premap_size>,<max>.

do_fork(): RLIMIT_NPROC check
...
1. mcexec sets RLIMIT_NPROC to the number of mcexec threads.
2. do_fork() gets the current number of threads by calling rusage function.
3. do_fork() returns -EAGAIN when the limit is exceeded.
