Okay after reading up in the README again I always forgot to set
MKMAINTAINERTOOLS=yes when building my tools.

Since I am cross-developing gentoo-linux-x86_64 to NetBSD/eco32 I simply
exported that variable.
After a while gettext horribly failed with a threaded build.
Single threaded build ends up in failure too:
nbmake: don't know how to make ../libuniname/libuniname.a. Stop

nbmake: stopped in
/hdd/home/okarin/eco32/netbsd-on-eco32/usr/obj/tools/gettext/build/gettext-tools/src

I have another team-member up to testing this on a native NetBSD-system.
Maybe this will shed some more light on tis.

Now this doesn't just happen for the eco32 but also for pmax.

My thought was the following:
If I get gettext to work maybe the rest will pull itself up. (I actually
have no idea if that is even possible)

With best regards,
