[PATCH] Makefile: Fix u-boot-nodtb.bin target
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.

Since this patch is applyied on master branch, I have error when I compile with the verbose option V=1.
I don't found a correction for this issue until now... except revert this commit.
For information: I use stm32mp1 platform = ARMv7 32bits I have the error:
scripts/Kbuild.include:220: *** Recursive variable 'echo-cmd' references itself (eventually). Stop. make[1]: *** Waiting for unfinished jobs.... make -f /local/home/frq07632/views/u-boot/scripts/Makefile.build obj=arch/arm/dts dtbs

Hello Patrick!
Now I was able to trigger this issue, but it seems to be present only sometimes. Calling make more times hides that issue, so it looks like something broken in Kconfig dependency generator for Makefiles... Or maybe something dependent on GNU make...
I played a bit with it and after changing following line in that patch
shell_cmd = { $(echo-cmd) $(cmd_$(1)); }
by
shell_cmd = { $(call echo-cmd,$(1)) $(cmd_$(1)); }
that issue disappeared. But because it triggered on my machine only sometimes, I do not know if it finally fixes it.
Could you please try this change? And do you have reproducer how to _always_ trigger it and not only sometimes?

on my machine (Ubuntu 18.04 / fast laptop with Core i7) it is 100% reproduce with: 1/ gcc version 9.2.1 20191025 (GNU Toolchain for the A-profile Architecture 9.2-2019.12 (arm-9.10))

I test it with the change:
-shell_cmd = { $(echo-cmd) $(cmd_$(1)); } +shell_cmd = { $(call echo-cmd, $(1)) $(cmd_$(1)); }
And I never reproduced the error again and command is correctly displayed with V=1:
arm-none-linux-gnueabihf-objcopy --gap-fill=0xff -j .text -j .secure_text -j .secure_data -j .rodata -j .hash -j .data -j .got -j .got.plt -j .u_boot_list -j .rel.dyn -j .binman_sym_table -j .text_rest -j .dtb.init.rodata -j .efi_runtime -j .efi_runtime_rel -O binary u-boot u-boot-nodtb.bin && { true; } || rm -f u-boot-nodtb.bin
or without option
OBJCOPY u-boot-nodtb.bin
So I think that the issue is fixed.
