4Subject: [PATCH] Makefile: add dependency from lib to arch/$(ARCH)/lib
5
6Top level Makefile starts separate "make" processes for each each
7subdirectory. lib/efi_loader apps now depend on lib.a from
8arch/$(ARCH)/lib if CONFIG_USE_PRIVATE_LIBGCC is enabled which creates
9a race conditions since dependency from lib/efi_loader EFI apps to
10arch/$(ARCH)/lib/lib.a is not explicit:

33
34The different "make" processes share common scripts/Makefile.build
35and scripts/Makefile.libs but since they are separate processes
36the Makefile rules can't add a dependency from lib/uefi_loader targets
37to arch/$(ARCH)/lib/lib.a. Or the file level dependency can be added but
38then "make" produces a too sparse error message which does not mention
39that one of the dependencies like arch/$(ARCH)/lib/lib.a was not found:
40
41make[3]: *** No rule to make target 'lib/efi_loader/helloworld.efi', needed by '__build'. Stop.
42
43Fix this dependency problem by building arch/$(ARCH)/lib before lib
44if CONFIG_USE_PRIVATE_LIBGCC was enabled.
45
46To reproduce the race condition more reliably, add a "sleep 10" delay
47before linker command cmd_link_l_target with 2025.07
48or to $(lib-target): target in scripts/Makefile.build with master branch
49after Kbuild update.

4Subject: [PATCH v3 1/2] Makefile scripts/Makefile.lib: fix *_efi.so dependency
5 to PLATFORM_LIBGCC
6
7When PLATFORM_LIBGCC was added to linker command it was not
8added to the dependency of the .so and other rules. Thus a build can
9try to link *_efi.so files before lib.a from PLATFORM_LIBGCC is available.

43
44Fix by introducing PLATFORM_LIBGCC_LIBA variable with only lib.a
45filename which is then used to add the dependency in rules which use
46PLATFORM_LIBGCC. This should not impact builds which don't set
47PLATFORM_LIBGCC_LIBA and PLATFORM_LIBGCC usage stays as is.
