jukivili closed T5256: libgcrypt, convert Intel syntax x86_64 assembly files to AT&T syntax as Resolved.
Problem with clang and these files was resolved by replacement of assembler macros with C preprocessor macros.

That might be helpful. But, on the other hand, if I had just googled the problem I was seeing I would have gotten answer quite fast.

Should we add this to the hints in the README? After all this does not seem to be the standard system compiler or it has not been properly setup as replacement.
jukivili added a comment to T5255: libgcrypt: build "error: invalid operand for instruction" when compiling with Clang & LTO.
Problem was that my build system was selecting "ar" and "ranlib", where as your build system selects "llvm-ar" and "llvm-ranlib".

Clang support Intel syntax after all, but not assembler macros that were used. Here's two patches that fix the configure.ac issue and removes use of assembly macros in Intel syntax assembly files:

Breakage appears to happen in configure.ac. When building with clang without LTO following check gives "no":

Both are affected. I updated to reflect that I tested the newer version
