Subject: linux-next: objtool hang/loop?

Hi Josh & Peter,

Yesterday (2021-07-27), one of my x86_64 randconfig build ran for
over 2 hours (it's a slow core i5 laptop and spinning rust media).
I killed it and reran the .config file today on linux-next-20210728.
I killed this one after 30 minutes on its last message:
  OBJTOOL vmlinux.o

This is a .config with # CONFIG_MODULES is not set.
vmlinux.o is 253 MB in size.
I see that using verbose make (V=1) won't help me any here.

The problematic (if it is a problem: maybe I didn't wait long
enough?) .config file is attached.  The gzipped vmlinux.o file is at:
  http://www.infradead.org/~rdunlap/vmlinux.o.gz

If there is a problem, I can test any patches...

thanks.
