Take a look into avr-libc's gcrt1.S. It has its own section.

No. It's just one line. I don't even know which avr architecture you use.

MCU: ATmega8 => avr4

cp /usr/local/avr/lib/ldscripts/avr4.x avr4-no-interrupts.x

delete the *(.vectors) line in avr4-no-interrupts.x

avr-gcc -Wl,--script=avr4-no-interrupts.x ..
