Yes, you are not supposed to ever handle crtX.o manually when using
avr-gcc.  Only if you decide to handle the entire linkage step
manually by explicitly calling avr-ld, this will pass any and all
responsibilites to you.

Again, you can easily watch all this by calling avr-gcc with the -v
flag: it'll tell you about which backend command it's calling, and
which arguments to call them with.
