Ard Biesheuvel c573a13f72 efi/libstub/x86: Work around LLVM ELF quirk build regression ... [ Upstream commit f77767ed5f ] When building the x86 EFI stub with Clang, the libstub Makefile rules that manipulate the ELF object files may throw an error like: STUBCPY drivers/firmware/efi/libstub/efi-stub-helper.stub.o strip: drivers/firmware/efi/libstub/efi-stub-helper.stub.o: Failed to find link section for section 10 objcopy: drivers/firmware/efi/libstub/efi-stub-helper.stub.o: Failed to find link section for section 10 This is the result of a LLVM feature [0] where symbol references are stored in a LLVM specific .llvm_addrsig section in a non-transparent way, causing generic ELF tools such as strip or objcopy to choke on them. So force the compiler not to emit these sections, by passing the appropriate command line option.
