#2606 linker build dependencies

[Philipp Klaus Krause]

There is a problem with the build dependencies for the linker. I noticed this after trying to enable debug output by uncommenting

//#define DEBUG_PRINT

in sdas/linksrc/lklibr.h. And not getting any debug output.

make after changing sdas/linksrc/lklibr.h does not rebuild the files that depend on lklibr.h (but changing the .c files themselves will). I dont know if the problem is there for other headers, too.
