OK, I understand that you also want the test to pass on native x86_64.
I'll try to find more information about the original objcopy problem and
make a fix that addresses both the build ID issue and the x86_64 issue.

Fair enough.  I've been helped by Fedora's debuginfo more than once.  

I understand it's OK to strip build ID from anything that is used in the
real boot (whether it's affected by the new objcopy bug or not), as we
want space saving and we cannot debug it in gdb.
