This seems entirely off-topic for libcdb-file-perl. Maybe open some bug
against pkg-js-tools?

If you refer to
https://sources.debian.org/src/pkg-js-tools/0.9.25/lib/Debian/Debhelper/Buildsystem/nodejs.pm/?hl=679#L679
then yes, that's wrong and should be using DEB_HOST_MULTIARCH.

In practical terms, the values only differ on any-i386.

$ dpkg-architecture -ai386
...
DEB_HOST_GNU_TYPE=i686-linux-gnu
DEB_HOST_MULTIARCH=i386-linux-gnu
...
$

When referring to /usr/lib/<triplet>, it's always DEB_HOST_MULTIARCH.
You should use DEB_HOST_GNU_TYPE for ./configure --host=<triplet> and
for <triplet>-<tool>.

Hope this helps

Helmut
