lang7/rust fails to build on i386?

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

All,

for a while pkgsrc updates have been halted on my i386 netbsd-8 machine 
because the rust build dies with

[...]

--manifest-path

--verbose --frozen

*** Error code 1

which, of course, blocks a firefox update.

Is this a known issue, or would there be local issues? My /etc/mk.conf 
does not have anything related.

Cheerio,
hauke
