While fixing #1030638, I have verified my patch[1] fixes mipsel as well.

I'll note that the FTBFS is caused by a test failure in test
"t.chown". stat(1) is used to check the expected owner of a file,
and the test reveals (I think) a wrapping problem.

I *think* the actual function called by stat(1) might not be wrapped
in the running stat(1) process, but I cannot tell if this is a
problem with the LD_PRELOAD approach or a missing wrapper or
something else.

Unfortunately most of the code seemingly relevant is "documented"
using words like "hack", "stuff" and "shuffle", making it harder to
follow than maybe necessary.

Bug#1024544: fakeroot: FTBFS on mipsel blocking fix for #1023286

Package: fakeroot
Version: 1.29-1
Severity: serious

Hi,

The fakeroot/1.30.1-1 FTBFS on mipsel (release arch) which blocks the 
fix for #1023286 from affecting mipsel binaries.


The #1023286 also seems to be source of a lot of a dbgsym packages
having the wrong ownership in them (see #1024261).  With
debhelper/13.11, the dbgsym packages will no longer be a problem but
we risk that the bug leaks into regular debs as well (no one has
tested for this).

Thanks,
~Niels
