Dmitry Chagin 3bdf68086d rtld: Add a stop indicator to rtld_start to satisfy unwinders on x86_64 
The right unwinding stop indicator should be CFI-undefined PC.
https://dwarfstd.org/doc/Dwarf3.pdf - page 118:
If a Return Address register is defined in the virtual unwind table,
and its rule is undefined (for example, by DW_CFA_undefined), then
there is no return address and no call address, and the virtual
unwind of stack activations is complete.

That is allows gdb and libunwind successfully stop when unwinding stack
from global constructors and destructors.
