As I am the one who submitted the patch for DYNFLAG="-Wl,-E", it's all my 
fault :-)

On my test machine I use gcc and gnu ld. After I read the message on 
samba-technical I found a machine which uses /usr/ccs/bin/ld and gcc, so I 
can see the problem.

I suggest checking if we use GNU ld:

How about this ?
