Hello.
Thank you for the release. I'm seeing a linking error during test build:

Can you please take a look?

Small analysis:

$ gcc test-nlist.o ../libelf/libelf.so
$ gcc ../libelf/libelf.so test-nlist.o

apparently gold is fine:
$ gcc ../libelf/libelf.so test-nlist.o -fuse-ld=gold
[ok]
$ objdump -t test-nlist.o | grep nlist
test-nlist.o: file format elf64-x86-64

May it be related to some order mentioned in

Thanks,
