After adding '-e', I get:
# ./loc2c-test -e testsuite/libexternalvar.so 0x1a70
./loc2c-test: dwfl_addrdie: address out of range
# ./loc2c-test -e testsuite/libexternalvar.so 0x1a70 libvar
./loc2c-test: dwfl_addrdie: address out of range
> and what does eu-readelf say about the lib_call function?

> $ eu-readelf -s testsuite/libexternalvar.so | grep lib_call
# eu-readelf -s testsuite/libexternalvar.so | grep lib_call
48: 000000000000062c 18 FUNC LOCAL DEFAULT 10 lib_call
