[PATCH v7 0/3] elf: Restore support for _r_debug interpositions and copy relocations

[Florian Weimer]

Version 7 fixes the comment issues Andreas identified, and attempts to
avoid an undefined reference to _r_debug in elf/tst-nolink-libc-2 on 32
bit Arm.

Tested on powerpc64le-linux-gnu and x86_64-linux-gnu.

Thanks,
Florian
