You need to compile with the following:

CONFIGURE_ARGS+= --disable-pie

This was caused by your setting of the following:

security.bsd.map_at_zero=0

You can reset that value to 1 and you should be alright to operate like 
normal otherwise you will have to compile samba over again with the above 
mentioned configure options.

Best regards.
