Mainly for backward compatibility. These proctools were originallly located in /usr/proc/bin since there was this concept of keeping various utility collections under different prefixes in Solaris. This gave rise to more confusion that any benefit at all and later things were changed in Solaris 10 and onwards to have most things in /usr/bin and GNU tools in /usr/gnu/bin. These links are present to retain backwards compatibility.
