Anything using host-qemu to help in cross-compilation cannot work: it is very likely that the kernel headers used to build the target toolchain are much more recent than the kernel running on the build machine. Since the Qemu user-mode emulation works by converting the target syscall into host syscall, it cannot work when kernel headers are more recent than the kernel version running on the build machine. I don't see how this can be solved, it is a fundamental problem in the approach. Thomas

Since you haven't given any further comments on this since March, the patch has been waiting in our patchwork queue. While waiting for (hopefully) some solution, or comment from you, I'll mark the patch as "Rejected" until we get to an agreement on how to solve the cpanminus problem. Thanks, Thomas
