aaa246f86f mcexec: change debug printf macros to be more tolerant to trivial format 
Enabling DEBUG fails to compile. It'd be easy to fix the dprintf to dprint
but this is just as generic and we can now use dprintf everywhere

4f2c1e07c1 Add ARCH variable to Makefiles

In executer/user/Makefile.in it was used before it was set.

b894619d1b 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.
