Actually, the linker relaxation code already considers cases where deletion of
the ret in call/ret or jmp/ret might be unsafe - just that it missed this
specific case.

The case being that GCC puts the array containing the addresses of the labels
in a separate section (.rodata). The safe ret deletion logic assumes that only
relocations in the local section (containing the ret) could potentially have
symbols whose values evaluate to the address containing the ret, but that is
not true in this case.

Looping over all sections in the BFD, and repeating the check for each section
fixes the problem (see attached patch).
