The mbr.bin and usbdisk.bin standalone blobs are currently generated using "objcopy -O binary", which does not process relocation records. For the i386 build, this does not matter since the section start address is zero and so the ".rel" relocation records are effectively no-ops anyway. For the x86_64 build, the ".rela" relocation records are not no-ops, since the addend is included as part of the relocation record (rather than inline). Using "objcopy -O binary" will silently discard the relocation records, with the result that all symbols are effectively given a value of zero. Fix by using "ld --oformat binary" instead of "objcopy -O binary" to generate mbr.bin and usbdisk.bin. Signed-off-by: Michael Brown <mcb30@ipxe.org>
