ldd(1) usually returns for ELF binaries output like this: libc.so.6 => /lib64/libc.so.6 (0x00007fbacd6ca000) But with glibc-hwcaps, the output could also be like this: libc.so.6 => /lib64/glibc-hwcaps/power9/libc-2.28.so (0x00007fffb5800000) See also: https://sourceware.org/pipermail/libc-alpha/2020-June/115250.html
