This change fixes two issues when building u-boot-nodtb.bin target:
Remove intermediate binary u-boot-nodtb.bin from disk when static_rela call (which modifies u-boot-nodtb.bin binary) failed. It is required because previous objcopy call creates binary and static_rela finish it.
Do not call static_rela cmd when u-boot-nodtb.bin binary was not created/updated by previous objcopy call.
Second fix would ensure that u-boot-nodtb.bin binary is not updated when all prerequisites were up-to-date. And therefore final binary u-boot.bin is not updated in case all prerequisites were not modified and were up-to-date.
Now running 'make SOURCE_DATE_EPOCH=0 u-boot.bin' second time now does not touch u-boot.bin binary in case nothing was modified, so GNU make can correctly detect that everything is up-to-date.
