Can you provide more details on what this last item means?
That means elfutils tests need the binary not stripped, so we need below
logic:
INHIBIT_PACKAGE_STRIP = "1"
INHIBIT_PACKAGE_DEBUG_SPLIT = "1"
Do you mean elfutils is generally broken without the symtab section?
That seems unusual? Or do you mean the tests need it to be present?
Not sure whether elfutils is broken, but at least it is broken with
regard to test part. If strip the binary, the test result:
Recipe | Passed| Failed | Skipped
elfutils | 184 | 15| 4
And all the failed case as below is because the binary is stripped.

For the test-nlist, the upstream also said the binary cannot be stripped
to guarantee the test pass as
https://sourceware.org/ml/elfutils-devel/2019-q2/msg00098.html and
https://sourceware.org/ml/elfutils-devel/2019-q2/msg00103.html
So to fix this kind of below failures, we need to make the binary not
stripped.

Not striping the binary at all is likely to cause a significant size
increase for elfutils and we want to avoid that, particularly if its
only to fix tests. We will probably have to find a different solution
(e.g. second copy with the symtab section in the ptest package, added
to PATH in the runner?)
During my test, if we strip the debug info to elfutils-dbg, first we
need to make elfutils-ptest rdepends on elfutils-dbg and second the test
still fails as above even the elfutils-dbg package deployed as below:
# pwd
/usr/lib64/elfutils/ptest
root@qemux86-64:/usr/lib64/elfutils/ptest# ls src/strip
src/strip
root@qemux86-64:/usr/lib64/elfutils/ptest# ls src/.debug/strip
src/.debug/strip
/.debug/strip64:/usr/lib64/elfutils/ptest# rpm -qf
/usr/lib64/elfutils/ptest/src/.debug/strip
elfutils-dbg-0.176-r0.core2_64
Thanks,
Cheers,
Richard
