Enabling of all possible targets broke ARM cross toolchain

Thanks for the report

I think it's inconvenient that objcopy has this behavior, and it does probably make sense to change it to not list all ARM architectures. That said, it seems like the above build calls dh_strip on an armel-cross architecture all package, which is not too common, and also calls it as a regular build instead of a cross-build which means that the hosts' strip gets called instead of the cross-strip.

It's probably a good idea to call dh_strip here as armel-cross_all packages are a bit special, but probably this should be called with dpkg-architecture args set to a cross build.

18:17 < hrw> slangasek: dh_strip checks for DEB_BUILD_GNU_TYPE/DEB_HOST_GNU_TYPE when it tries to find cross tools and it is ok. but for cross-gcc it is only partially good as we generate both host binaries (dh-strip is fine) and cross ones (dh-strip fails)
18:17 < slangasek> hrw: right
18:18 < hrw> I think that we can change gcc to manually strip using cross-strip for cross builds but would it be proper way?
18:19 < slangasek> hrw: lool seems to have thoughts about what dh_strip should do here; I think he has a point that if you're running dh_strip on an arch: all package, you probably want the binutils-multiarch version
18:20 < steev> i ask about it being a mirror because i can't seem to check out Freescale's repo currently
18:20 < hrw> slangasek: but for strip-multiarch I need to know what I will strip cause now it just fail
18:21 < slangasek> hrw: well, I don't think gcc manually using the cross-strip sounds very correct. what other options are there? Can we revert these latest changes to binutils-multiarch?
18:22 < hrw> slangasek: that would be simplest solution I think
18:22 < hrw> we can look at returning to it during 11.10
18:37 < hrw> slangasek: DEB_HOST_GNU_TYPE=arm-linux-gnueabi dh_strip -plibgcc1-armel-cross --dbg-package=libgcc1-dbg-armel-cross
18:37 < hrw> slangasek: that works and is change into gcc packaging to set DEB_HOST_GNU_TYPE=DEB_TARGET_GNU_TYPE
18:38 < hrw> slangasek: arm-linux-gnueabi-objcopy --only-keep-debug debian/libgcc1-armel-cross/usr/arm-linux-gnueabi/lib/libgcc_s.so.1 debian/libgcc1-dbg-armel-cross/usr/lib/debug//usr/arm-linux-gnueabi/lib/libgcc_s.so.1

Thats added to not forget about it. Change was done to gcc/debian/rules.d/binary-libgcc.mk packaging rules.

This bug was fixed in the package binutils - 2.21.0.20110216-1ubuntu3

---------------
binutils (2.21.0.20110216-1ubuntu3) natty; urgency=low

  * Read multiarch targets from the first column of /usr/share/dpkg/archtable;
    it's not the ideal list, but it's better than a hardcoded list and
    enabling all targets was breaking too many tools; LP: #726428.
