* gnu-versions.h: New file.

* hurd/hurd/userlink.h (_hurd_userlink_link): Properly set
LINK->resource.next->resource.prevp when appropriate, not
LINK->resource.next->thread.prevp!!!
* Makerules (lib%.so: lib%_pic.a): Moved this rule to after
installation rules.
* sysdeps/mach/sysdep.h [HAVE_ELF] (ENTRY): Redefine this macro so
it uses the `.type' directive, which is necessary for shared
libraries to work properly.

lt_interpreter, first undo relocation done during bootstrapping.

not refer to any functions not defined in libc.

properly, and deal with a send right dying while we try to copy
