INN 2.6.4 util/inndf test 6 gives different result on ppc64le on Fedora

Hi all,
while preparing an update to Fedora inn package (to 2.6.4),
I encountered this test failure on ppc64le only:
[...]
util/inndf..............FAILED 6

Closer inspection shows:
[mockbuild@e18bd93d051b44ce8fb7851e05850239 tests]$ LD_LIBRARY_PATH=/builddir/build/BUILDROOT/inn-2.6.4-1.fc35.ppc64le/usr/lib64 ./runtests util/inndf -o
6
ok 1 
ok 2 
ok 3 
ok 4 
ok 5 
3.33% overview space used
not ok 6 
[mockbuild@e18bd93d051b44ce8fb7851e05850239 tests]$ 

I worked around this by patching the expected result to the above value
on ppc64le only, but perhaps there's a better solution? Could this be
related to the fact that ppc64le uses 64k page size instead of 4k?

Example failed build (on Fedora 34 branch):

(check build.log)
