Seems you already got your answer to the build question solved.

Note that there is some code in elfutils git that handles .debug_frame
for ARM, but not yet code for handling EXIDX tables. For non-debug
unwinding ARM uses EXIDX tables, not .eh_frames. Handling EXIDX tables
is probably easiest done by translating them to CFI. In case you want to
do unwinding using libdw without .debug_frame available.
For AARCH64 there is some code available on my branch:
Which might or might not work. I need to get access again to a aarch64
setup to do some more testing before moving this to master.
