Is there any possibility how to suppress dumping emacs?
Shall I add something to ./configure script or even to make?

You could try adding -DCANNOT_DUMP=1 to preprocessor command-line
switches.  But it would be much better if you try figuring out why it
segfaults, then we might be able to come up with a solution that
preserves the dumping capability.

Dumping under the name emacs
emacs: Program segment above .bss in /builddir/build/BUILD/emacs-24.3/build-gtk/src/temacs
make[2]: *** [bootstrap-emacs] Error 1
