FWIW, I don't think that either gaur or prairiedog need be factored into
this conversation. They cannot build ninja at all for lack of <spawn.h>,
so whether they could run meson is pretty much beside the point.

(I wonder if we should stick in a configure test for <spawn.h>,
just to see if anything else doesn't have it?)

We should worry a little more about Solaris and AIX, but even there I
think it's largely up to the platform owner whether they've updated
python to something modern. If it isn't, you need to move the goalposts
back some more :-(. As of today I see the following pre-3.6 pythons
in the buildfarm, exclusive of mine:

skate 3.2.3
snapper 3.2.3
topminnow 3.4.2
hornet 3.4.3
sungazer 3.4.3
wrasse 3.4.3
shelduck 3.4.10
curculio 3.5.1
hoverfly 3.5.1
batfish 3.5.2
spurfowl 3.5.2
cuon 3.5.2
ayu 3.5.3
chimaera 3.5.3
chipmunk 3.5.3
grison 3.5.3
mussurana 3.5.3
tadarida 3.5.3
urocryon 3.5.3
