In this bug report, you mention using LLVM=1. Does the issue happen if
you use GNU ld (ld.bfd) via LD (i.e., LD=powerpc64le-linux-gnu-ld or
equivalent) over ld.lld from LLVM=1? This sounds more likely to be a
linker difference rather than a compiler difference.

Thank you for the insight.

Yes, when using powerpc64le-linux-gnu-ld linker .interp section is not
emitted.

Command:
$ make LLVM=1 ARCH=powerpc LD=powerpc64le-linux-gnu-ld -j 8 zImage
$ llvm-readelf -p .comment vmlinux

String dump of section '.comment':
[     0] clang version 22.0.0git (https://github.com/llvm/llvm-project.git 7314565281ec28b745502c3f429fd431e16673eb)

$ llvm-readelf -p .interp vmlinux
llvm-readelf: warning: 'vmlinux': could not find section '.interp'

Thanks for confirming. Does this fix the issue for you? It appears to
work for me.

Cheers,
Nathan
