It turned out that this is an SH specific readelf problem.
readelf loads the .eh_frame section and fixes the contents
according to rela addends with debug_apply_rela_addends when
the target uses RELA. Although SH uses RELA relocations,
it doesn't use their addend fields and uses in place values.
Then debug_apply_rela_addends wrongly clears some entries in
FDE with null addends. I'm testing the attached patch.
