Interestingly, this seems to be due to a bug introduced in the
upstream kernel sometime late last week. We had a successful build on
the 14th with CONFIG_DEBUG_INFO_BTF on, by Monday, this was failing.
for me it was introduced with recent gcc update to:
$ gcc --version
gcc (GCC) 10.2.1 20201005 (Red Hat 10.2.1-5)
