Automating the master build from scratch requires some annoying

thanks to 1ea1646e6f224dbc5b3922bb3c65aab4d71a9cb9. This can be worked
around by running the requisite commands first, i.e.,
rm -f po-docs/podfiles && make -C po-docs update-po && make
But after that, there still appears to be a race in the po-docs
build (reproduced on -j12 on an E5-1650 v2):
make[2]: Entering directory 'libguestfs-git/src/libguestfs/po-docs'
Making all in ja
make[3]: Entering directory 'libguestfs-git/src/libguestfs/po-docs/ja'
make[3]: *** No rule to make target 'guestfish-actions.pod', needed by
'guestfish.1'. Stop.
This appears to go away if you set .NOTPARALLEL in all of po-docs.

The bug that was causing 1ea1646e6 in the first place was subtle, and
I wish I'd written down more detail about exactly why (I thought) it
was impossible to fix ...
Anyway, adding .NOTPARALLEL may be the right fix, but I can't see how
it will help unless we also revert 1ea1646e6. So at minimum you need
to send a revert commit as well.
Also we might need to add .NOTPARALLEL to po-docs/language.mk too.
Also it needs a big comment explaining exactly why we are doing this,
since what will inevitably happen later is someone will wonder why the
file has .NOTPARALLEL and try to remove it.
Rich.
