[arch-projects] [devtools] [PATCH] $pacconf_cmd in arch-nspawn should use the provided config file (-C)

[arch at eckner.net]

From: Erich Eckner <git at eckner.net>

If arch-nspawn is called with -C, pacman inside the chroot will use the
provided configuration file. This should also be the case for
$pacconf_cmd when determining the remote servers.

For example, Arch Linux 32 provides separate pacman configurations which
use /etc/pacman.d/mirrorlist32 as mirrorlist for their build commands
(extra-i686-build, etc.). This way, we can build i686 and x86_64
packages on the same x86_64 host with very minimal changes to devtools.
