If you run avr-gcc with the -v option you can see exactly what it
passes down to avr-ld.
For example:
Using:
avr-gcc -v -mmcu=atmega128 -o hello.elf hello.o
you'll see that -lc and -lgcc are passed into avr-ld. If you use:
avr-gcc -v -mmcu=atmega128 -o hello.elf -nostdlib hello.o
you'll

I would like to use GCC and skip the c-runtime init module completely (I'll
initialize my few variables at the start of "main()"). I am writing a
bootloader, of course...
I vaguely recall doing this in the past, but cannot remember how it is done,
nor find it in the libc FAQ.
TIA.
