use OCRAM_S for interrupt vectors by default

The Cortex-M4 core starts executing at 0x00000000, which is OCRAM_S.
So far the bootloader (bootaux) copied the reset vector and the initial
stack pointer to that location, however, this does not work well when
using debuggers. Also, newer U-Boot support elf loading, which allow to
load the reset vector directly to the right location. It also safes some
bytes in the area where the firmware is stored.

This basically mandantes to use elf files since bin firmware files can
not be sparse... Hence disable building bin files by default.

Preserve the old linker files with _bin extension in case bin files are
still preferred.
