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)

Made changes according to feedback from @Mic92 such as moving the
`rewriteSections` inline into every method.
Improved `replace-add-needed.sh` to work with musl libc
