Elaborating:
The situation this patch addresses a forward cross build of gcc that
sets with_deps_on_target_arch_pkgs=yes. In this case gcc emits (among
others) a libgcc1:arm64 package. (Taking DEB_TARGET_ARCH=arm64 as an
example, but it works the same for other architectures.) This
libgcc1:arm64 package has a Depends line mentioning gcc-4.8-base.
However gcc-4.8-base:arm64 is not among the packages that were built.
Thus installation of libgcc1:arm64 fails with a dependency error. The
gcc-4.8-base:amd64 package cannot be used to satisfy this dependency,
because it is marked M-A:same.
The proposed fix is to cause with_deps_on_target_arch_pkgs=yes to build
gcc-4.8-base:arm64, such that both can be properly installed.
If this is not the desired fix, then maybe libgcc1:arm64 should drop its
dependency on the non-existent gcc-4.8-base:arm64 package?
Do you need a build log exposing this issue? I can temporarily drop the
patch from rebootstrap.
Note that the patch applies to gcc-4.9 as well solving the very same
issue there.
Hope this helps
Helmut
