* 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 :-) git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30545 a95241bf-73f2-0310-859d-f6bbb57e9c96
