According to the manpage of fseek(), which is identical to fseeko()
apart from the offset data type:

ERRORS
       [...]
       EINVAL The whence argument to fseek() was not SEEK_SET,
       SEEK_END, or SEEK_CUR.  Or: the resulting file offset would
       be negative.

I suspect that something is calling fseeko() with a negative offset.

I'd recommend doing an strace on the specific test binary that
fails on a porterbox (e.g. armhf) + on amd64 for comparison and
then look for the offending fseeko() call. That might help isolate
the issue.

Christian
