Which, if I read the bug correctly, is a yet another case of a bogus build system looking at characteristics of the machine it's compiled on rather than baseline of the arch. And, per your own work, it's +patch +fixed-upstream. > I have not heard from the ppc64el porters, but I suspect ppc64 will > not be a release arch.

What would you need ppc64 for? Unlike i386, powerpc includes 64-bit kernels so users don't need multiarch: powerpc has: linux-image-4.7.0-1-powerpc - Linux 4.7 for uniprocessor 32-bit PowerPC (signed) linux-image-4.7.0-1-powerpc-smp - Linux 4.7 for multiprocessor 32-bit PowerPC (signed) linux-image-4.7.0-1-powerpc64 - Linux 4.7 for 64-bit PowerPC (signed) i386 has: linux-image-4.7.0-1-686-pae-unsigned - Linux 4.7 for modern PCs linux-image-4.7.0-1-686-unsigned - Linux 4.7 for older PCs linux-image-4.7.0-1-grsec-686-pae - Linux 4.7 for modern PCs, Grsecurity protection linux-image-4.7.0-1-686 - Linux 4.7 for older PCs (signed) linux-image-4.7.0-1-686-pae - Linux 4.7 for modern PCs (signed) Note the joke: "for modern PCs". Unless you do embedded it takes some serious dumpster diving to find a machine not better served by an -amd64 kernel (and thus multiarch). The i386 architecture is not self-contained, powerpc is. Thus, there is no need for ppc64 (userland), as long as powerpc has the toolchain to build 64-bit kernels. And that's a primary target for gcc upstream. -- A MAP07 (Dead Simple) raspberry tincture recipe: 0.5l 95% alcohol, 1kg raspberries, 0.4kg sugar; put into a big jar for 1 month. Filter out and throw away the fruits (can dump them into a cake, etc), let the drink age at least 3-6 months.
