>Environment:
Linux debian-mips 3.2.0-4-4kc-malta #1 Debian 3.2.51-1 mips GNU/Linux
>Description:
bootstrap's build_package()'s bmake command is missing a MACHINE_ARCH=, which along with 'uname -m' responding as 'mips' instead of 'mipseb' on linux has been causing bootstrap to fail.

This issue probably doesn't affect little-endian MIPS devices since linux refers to those as 'mipsel' just as pkgsrc does.

It should be noted however that the supplied patch ONLY fixes this for 32 bit, big-endian MIPS devices. big-endian MIPS64 devices will run into the same problem, as might builds on certain ARM devices
>How-To-Repeat:
Grab the 3.2.0 kernel and Debian Wheezy image from here:

http://people.debian.org/~aurel32/qemu/mips/

Drop them in a directory, and run it via qemu with a command like:

qemu-system-mips -m 256 -M malta \
-kernel vmlinux-3.2.0-4-4kc-malta \
-hda debian_wheezy_mips_standard.qcow2 \
-append "root=/dev/sda1 console=tty0 console=ttyS0,115200n8" \
-netdev tap,id=mainnet -device pcnet,netdev=mainnet \
-chardev pty,id=charserial0 \
-device isa-serial,chardev=charserial0,id=serial0 \
-chardev socket,id=charmonitor,path=/tmp/mips.monitor,server,nowait \
-vnc 0.0.0.0:30

For networking functionality, a nic attached to a network card needs to be a member of a bridge, and the tap interface created by qemu-system-mips also needs to be added to it. You're on your own for creating the bridge interface since it varies by distro, but the lazy way to automatically add the tap interface to it when qemu starts up is to drop some lines into an /etc/qemu-ifup script along the lines of:

#!/bin/bash

ifconfig $1 up
brctl addif br0 $1

exit 0


From there, you might have to install build-essentials, cvs, and other pre-requisites, but it should be mostly business as usual as far as getting to this failure point from there.
>Fix:
The fix involves adding MACHINE_ARCH=$machine_arch to the list of bmake arguments in build_package(), as well as adding "-e 's/mips$/mipseb/'" to the machine_arch= line under the Linux section.

The following patch does both:

 That PR has broader scope.
 This PR is about practical problem of bootstrapping on some linux-based system.

 No; the idea was to commit this fix before the freeze, and then rework
 the script afterwards along the lines of 48906, but it looks like we
 didn't make it in time. :-|

I can confirm bootstrap works fine on a franken-debian
squeeze (EdgeOS) on big endian mips. let me know if
you still have different issues.
