hadn't noticed this either. If you execute ld, it gives a 
help screen, telling you that it will (among other things) 
launch executables. eg

igloo:/lib# ./ld-2.3.5.so /usr/bin/ls libc.so.*
libc.so.6

(apparently maintainers need to do this.)

on my slackware system, most of the libraries are 755, but
they segv on execution.
