The difference is in intention (both are ELF these days). /bin/ls is an "executable", /lib/x86_64-linux-gnu/libc.so.6 is a lib (yes, this one has an entry point, you can invoke it from the command line). While enabling PIC for libs has been done for a long time (IIRC the first motivator was limited address space under 32 bit) and always seemed a Good Idea(TM), for the executables I think it's ASLR what brought a motivation with it. But I might be wrong.
