Nathan,
at least 2 of those tests is not BE (big-endian) friendly:
mator@gcc203:~/util-linux.git/tests$ ./run.sh misc/pipesz
-------------------- util-linux regression tests --------------------
For development purpose only.
Don't execute on production system!
kernel: 5.15.0-2-powerpc64
options: --srcdir=/home/mator/util-linux.git/tests/.. \
--builddir=/home/mator/util-linux.git/tests/..
misc: pipesz ...
: set-fd-bad ... OK
: set-fd ... OK
: set-file-bad ... OK
: set-file ... OK
: get-fd-bad ... OK
: get-fd ... FAILED (misc/pipesz-get-fd)
: get-file-bad ... OK
: get-file ... FAILED (misc/pipesz-get-file)
: pipe-max-size ... OK

... FAILED (2 from 10 sub-tests)
---------------------------------------------------------------------
1 tests of 1 FAILED
misc/pipesz
---------------------------------------------------------------------
running on a sparc64 (gcc202) and on powerpc64 (gcc203) machines :
gcc202:~/util-linux$ echo -n | ./pipesz --check --get --stdin
fd 0 131072 0
gcc203:~/util-linux.git$ echo -n | ./pipesz --check --get --stdin
fd 0 1048576 0
So on x86_64 tests expect stdin file to be 64Kb:
gcc202:~/util-linux$ cat tests/expected/misc/pipesz-get-file
/dev/stdin 65536 0
but on sparc64 it is 128Kb and on powerpc64 it is 1Mb...
