Jörg, would it help to make ./crt1/gcrt1.S:__vectors weak so that
user can provide his own vector table?

With 1.7.1 an error will occur if one tries to:

main.o: In function `__vectors':
main.c:(.vectors+0x0): multiple definition of `__vectors'
./bin/../lib/gcc/avr/4.7.0/../../../../avr/lib/avr5/crtm168.o:../../../../../../source/avr-libc-1.7.1/crt1/gcrt1.S:52: 
first defined here
./bin/../lib/gcc/avr/4.7.0/../../../../avr/bin/ld.exe: Disabling 
relaxation: it will not work with multiple definitions
collect2.exe: error: ld returned 1 exit status
