> I build Perl successfully with qemu-arm and qemu-mips,
> the problem occurs with qemu-i386 and qemu-x86_64,
> with a qemu-i386 version 1.2.0 built with Buildroot and with a
> qemu-i386 version 1.0.50 which comes my distro Ubuntu 12.04 LTS.

> Other bad new, these days, the homepage of Qemu (http://wiki.qemu.org) is down.
