I added the -b parameter, and then gcc started to produce segfaults.

Segfault:
*** glibc detected *** /usr/x86_64-pc-linux-gnu/gcc-bin/4.1.1/gcc: realloc(): invalid next size: 0x0000000000528d10 ***
make[6]: *** [list.o] Speicherzugriffsfehler

Commandline:
   gcc -b elf_x86_64 -g -c -nostdinc -fno-leading-underscore -fno-omit-frame-pointer -Wall -fno-strict-aliasing -O0 -save-temps-I . -I- $INCLUDES

Note you most likely don't have a x86_64-elf compiler installed anyways but we should not be crashing.

-b and -V were removed:
