This is a giant patch that splits the linker scripts for libraries, modules and executables into
the architecture-dependent scripts to facilitate building syslinux modules/executables
for i386 and x86_64 environments. The x86_64 linker scripts are derived from the earlier i386
counterparts.
Subdirectories i386 and x86_64 hold the respective linker scripts mentioned below.
com32/lib/sylinux.ld
com32/lib/elf.ld
core/syslinux.ld
efi/syslinux.ld
mbr/mbr.ld
memdisk/memdisk.ld
Remanants of the unused old i386-only files, if any, need to be pruned.
