Comment 3 Alexandre Ferreira 2018-11-21 20:50:47 UTC
I think this is related to this bug. Using dev-libs/elfutils-0.175, the kernel 4.20.0-rc3 compilation fails with the error and downgrading to 0.173 compiles OK:

Apologies for the noise but I can confirm this. ZFS failed to upgrade for me today. Thinking the kernel might have been at fault I tried to re-compile it and encountered similar errors.

Searching for the problem shows at least one other person with the same issue (https://unix.stackexchange.com/questions/483434/objdump-file-format-not-recognized).

Could this please be masked until it's resolved? Breaking the kernel compilation is a serious issue.

Can you file a separate bug?

Managed to reproduce it locally as:
    USE=test FEATURES=test CFLAGS="-Og" emerge -v1 elfutils

For comparison the below works:
    USE=test FEATURES=test CFLAGS="-O2" emerge -v1 elfutils
