Bug#712001: debhelper: dh_strip wants non-existent i486-linux-gnu-strip tool

[Francois Gouget]

Package: debhelper
Version: 9.20120909
Severity: normal

Dear Maintainer,

I work on an i386 Debian package which I compile on an amd64 host. I do this by setting CC="gcc -m32" and calling 'dpkg-buildpackage -ai386' which gives me binaries of the right type.
But if I call dh_strip I get the following error:

+ dh_strip
Can't exec "i486-linux-gnu-strip": No such file or directory at /usr/share/perl5/Debian/Debhelper/Dh_Lib.pm line 215.
dh_strip: i486-linux-gnu-strip --remove-section=.comment --remove-section=.note debian/teststrip/usr/bin/hello failed to to execute: No such file or directory
dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2


I checked in Debian's package archive and none of the packages installs an '*-linux-gnu-strip' file. So dh_strip's expectations that it can find such a file seem mistaken. Besides plain old 'strip' works just fine in this case.

I have uploaded a test package to:
http://fgouget.free.fr/bugs/teststrip_1.0-1.tar.gz

To reproduce this bug just run './build' in the teststrip-1.0 directory on an amd64 system that has the gcc-multilib package.

All that dh_strip knows is that dpkg-architecture is returning
values that indicate there is cross compilation in process,
and that prefixing the command with DEB_HOST_GNU_TYPE
is the standard way to get a program that is capable of handling this.

You may have a bug in dpkg-dev here, I don't know.
