Applied patch by PulkoMandy, adjusted and extended by myself:

* integrating most of the locale kit into the build (and image)
* removed LocaleBuild.h and _IMPEXP_LOCALE since that does not make
  sense for elf (which usually exports all symbols anyway)
* added a couple of locale kit related pseudo targets for convenience
Hey, some of that stuff already seems to work :-)
