I tried someone's prepcore from CentOS 5.5 on a spotless extract of
4.03 and it worked.  The sequence of execution for pxelinux.0 is nasm,
ld, objdump, perl, objcopy, prepcore.  I used the make output to
backtrace one command at a time from his intermediate binaries and
found that redoing the ld step was what was needed to get it to work
on my build system.

Aaron, after changing to the latest binutils, did you either start
from a fresh extracted directory or clean it up (probably needs 'make
spotless', at least in core/, just to be sure)?
