5.14-rc0: regression when compiling tools/objtool

5.14-rc0: regression when compiling tools/objtool

Hi!

I'm getting build errors trying to build 5.14-rc0. Earlier -rc0
releases built okay. This is 64-bit x86 build, 32-bit x86 and arm
build okay for me, too. Attaching config, as it may be related?

Best regards,						pavel

This is quite annoying, as I'd like to try 5.14. Problem is not fixed
in -next, either...

Installing libelf-dev fixed / worked around the problem.
