eu-addr2line -i option to display inline functions doesn't work with LTO (-flto) and Dwarf enabled.

Issue

Using eu-addr2line -i option fails to display inline functions.

Example usage:

scl enable gcc-toolset-11 'gcc -O2 -flto -gdwarf-5 -g sample.c'

scl enable gcc-toolset-11 'eu-addr2line  -fCi -e a.out 0x401055'

Output Received:

"main
</PATH/TO>/elfutils/sample.c:6:5"

Output Expected :

# "FunctionToInline1
#</PATH/TO>/elfutils/sample.c:6
# FunctionToInline2
# </PATH/TO>/elfutils/sample.c:34
# FunctionToInline3
# </PATH/TO>/elfutils/sample.c:39
# FunctionToInline4
# </PATH/TO>/elfutils/sample.c:43
# FunctionToInline5
# </PATH/TO>/elfutils/sample.c:47
# FunctionToInline6
# </PATH/TO>/elfutils/sample.c:51
# main
