Hmm, no, it still works without --force:

$ dd if=/dev/null of=f bs=1 seek=30M && 
../build/multibuild-1650/linux/parted-3.0.136-1f80/parted/parted -s f mklabel 
gpt && /sbin/mkswap f && echo ok

mkswap: f: warning: don't erase bootbits sectors
        (gpt partition table detected). Use -f to force.
Setting up swapspace version 1, size = 30716 KiB
kein Label, UUID=e38425cd-369b-4a84-8d3e-4097f8e39110
ok

No, this patch does not fix the problem, but it gives a clue to the cause:

$ make check -C tests TESTS=t9050-partition-table-types.sh VERBOSE=yes
...
+ echo mkswap:bsd
mkswap:bsd
+ case $i in
+ mkswap -f f
./t9050-partition-table-types.sh: line 44: mkswap: command not found
+ fail=1
...

So, the reason was that 'mkswap' is not found in $PATH. (It's in /sbin,
which is not in $PATH of a non-root user in this distro.)
