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':

$ 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

Hello Nathan,
It does solve the problem, but with GNU linker it would work even
without this change.
