(and aside from a warning "i686-linux-gnu-ld.bfd: warning: cannot find entry
symbol _start; defaulting to 0000000008048094", succeeded.
correction: i had added one too many "0s" onto the evil python command.
however after correction, the results are exactly the same:
debian-i386-chroot$ python evil_linker_torture.py 80 40 20 80000000
* make maing FAILs
* make main SUCCEEDs (except only using 85mb for the linker phase)
so this is far more complex and involved than it first appears.
