Hello,

On systems (QNX) that have ldd residing in libc, 
svr4_current_sos will add libc twice. Once while walking the 
linkmap and second time from r_ldsomap.

This patch adds check if ldsolib has already been added and 
if so, prevents adding duplicate entry.


Tested on linux - i386, no regressions; however, it would be 
good if someone could test for regressions on Solaris.


Thanks,

to solist
if already added.
