cp2k build intel compilers

[Alfio Lazzaro]

Probably all is too much...
You can use 

-check bounds -check pointers

(see ifort --help for more options).

At this point, I don't have any other suggestion. As a last comment, is 
there any reason why you want to use the intel compiler? CP2K shows good 
performance with GCC too (linking with MKL)...
