Was quite obvious but I've missed it, default debug level have been 
changed since 4.11.4 so adding/changing:

     --enable-error_print \
     --disable-warning_print \
     --enable-debug-prints=no \

gets rid of all warnings except of errors so on ADSL even with ReTx 
enabled console is silent and CPU usage dropped down to earlier level, I 
cannot test VDSL so if anyone can check it and post some results. 
Working with newest binary xcpe_574306_571801 from TP-LINK.

Newest trunk with patches from xdarklight, packages from DrayTek.
