Fix powerpc, mips64, and s390x boards under qemu.

Collate mips variants handling (presumably supporting all 4 theoretical
ones, I should build a 64 bit little endian toolchain next time).

I don't know why powerpc needs CONFIG_NET_VENDOR_NATSEMI _and_
CONFIG_NET_VENDOR_8390, how many vendors can one chip have?

I don't know why s390 was space separating consoles on the same line
of /sys/class/tty/console/active instead of doing one per line like
other architectures. (Also removed the redundant console to avoid confusion.)

In or1k I moved the NAME="value" outside the $(be2csv) so the quotes
don't need to be escaped multiple times (same as sh2eb).
