Code completion search paths

Ok, I tried to set avr-gcc in the cmake settings dialog and the same
problem happens and yes in the avr include files have a lot of µC model
specific stuff, separated with ifdefs, in it.

But playing with the settings I figured out another problem with a simple C
Cmake project: When using time.h some functions like time() are not
recognized until time.h was opened once in kdevelop.

Another thing I found out is that kdevelop has settings for make and also a
settings how many threads it should use (-j), it would be great if kdevelop
would set this setting per default to the core count of the CPU.
