aa7cb970c4 ihk_os_getrusage(): Compile LWK-specific results in mcctrl 
1. User asks mcctrl for the result via ihk_os_getrusage() with passing void *
2. mcctrl compiles the results and passes them to the user
3. User interprets it by using the type defined in the LWK-specific header

0942bf0ce0 make dkprintf() evaluate its parameters always 
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled.  Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".
