I think that as of commit 7293ddf325b149cae60d3abe7199d08f196bd2b9
(so, quite some time ago), we are supposed to only be using the
in-tree XDR bits, at least for userspace builds.  So it should be
easy to resolve this issue by just removing the offending include
directives -- I took a stab in the chain of patches ending at
https://gerrit.openafs.org/#/c/12802/ .

Well, it looks like 2.26 is only in debian experimental so far, so
my systems (on unstable) haven't picked it up yet.  Could you give
the above patches a try and see if they help?

Thanks,
