That code is not supposed to be compiled at all in shared libc, only
static, and for static there is no "ld-linux". Also the dynamic linker
should be; if it's using ld-linux that's a foreign
dynamic linker that's not going to work.

Sorry, I misread the address column as the instruction encoding when I
saw just 4 hex digits. :-) So that's not the issue.

Can you dump the address range for __init_array_start at runtime in
gdb using the x command?
