make sys/procfs.h mostly work on most archs these structures are purely for use by trace/debug tools and tools working with core files. the definition of fpregset_t, which was previously here, has been removed because it was wrong; fpregset_t should be the type used in mcontext_t, not the type used in ptrace/core stuff.
