sh: Terminate .eh_frame in VDSO with a 4-byte 0.
It's assumed that .eh_frame is terminated with 4-byte 0 in shared
libraries and executable. It seems to be the case for VDSOs too.
Without this terminator, I saw failures when unwinding from VDSO,
though I don't know how other architectures handle this issue.
For the normal libs, crtendS.o gives this terminator. We can use
such terminating objects. Or we can add a 4-byte 0 with modifying
the linker script like as the patch below.
