Trying to compile and run `core` with a custom compiler

The .bss section is part of the ELF (ld.lib.so) and should be accessible once the ELF is loaded.

While I generally agree that the ELF loader has to prepare a zero’d BSS, I disagree that ld.lib.so is of any relevance as core-linux crasshes. Please correct me if I’m mistaken.
