Setting LD can be done on the make command line (you shouldn't
modify any sources for this). I don't think, however, that using a
mingw targeting binary will work, as the *same* ld will be used to
link the normal ELF executable (ending up as xen.gz). You should
use a Linux linker (i.e. defaulting to ELF) that *also* supports
i386pep. (Building binutils is, btw, a pretty simple process, so I
don't see why you're not just doing that - all customization you
need is adding "--enable-targets=x86_64-pep" to the configure
script invocation command line.)
