I don't think it is worth spending too much time getting cpanminus to
work with host-qemu. The entire idea of using host-qemu is broken due
to the potential incompatibility between the kernel headers used to
build the target C library and applications and the kernel currently
running on the build machine.
So any usage of host-qemu to do cross-compilation is doomed to fail,
unless we force very old kernel headers versions.
