Looking at https://bugzilla.redhat.com/show_bug.cgi?id=1211357 it deliberately uses nested functions and porting to clang will need to happen upstream.
Filed upstream as https://sourceware.org/PR24964
The next elfutils release should able to compile with clang. There is only one nested function in current code base.

*** Bug 793188 has been marked as a duplicate of this bug. ***
One more patch is needed to drop the unnecessary configure check, I've sent a patch for it [1] but otherwise Clang builds work now with latest mainline dev branch which will become v0.186. [1] https://sourceware.org/pipermail/elfutils-devel/2021q3/004033.html
This should've been sorted by https://gitweb.gentoo.org/repo/gentoo.git/commit/dev-libs/elfutils?id=388d62376b0d53e78d347ab890e2b8742aea2e23 AFAIK.
