[PATCH] uml: eliminate anonymous union and clean up symlink lossage
This gives a name to the anonymous union introduced in skas-hold-own-ldt, allowing to build on a wider range of gccs. It also removes ldt.h, which somehow became real, and replaces it with a symlink, and creates ldt-x86_64.h as a copy of ldt-i386.h for now.
