[Pkg-lxde-maintainers] Bug#890369: libfm FTCBFS: tries to run host arch tools while building documentation

[Helmut Grohne]

Source: libfm
Version: 1.2.5-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

libfm fails to cross build from source, because it tries and fails to
run /<<PKGBUILDDIR>>/docs/reference/libfm/libfm-scan. That's part of the
documentation, which resides in an Arch:all package and poses the
question why we run it at all in an arch-only build. The build
unconditionally passes --enable-gtk-doc to configure. I suggest changing
it to only pass that when libfm-doc is built. This can be complex
involving arch-only/indep-only/both builds and stage1 interaction. Thus
the easiest way is to let dh_listpackages tell whether we actually build
libfm-doc and only then pass the flag. Please consider applying the
attached patch. Testing it was not fully possible due to #876614.
