Clarification: not the same, but something close. At least there are multiple .eh_frame sections in output.

As far I understand what we need for this experiment is for each text section emit its own .eh_frame and set
SHF_LINK_ORDER and sh_link field for the latter pointing to .text section. Looks code from patch above
can be adopted to do that.

George.
