Running on embedded hardware

Nice router.  The CPU is a 260 MHz MIPS core from Broadcom that
implements almost all of the MIPS32 instruction set (the one exception
being the WAIT instruction).

Switch to Kamikaze.  It's much more pleasant to work with, and I've
found it to be somewhat more stable than Whiterussian.

You're cross-compiling, so you'll probably want to say something like

  CC=mipsel-linux-gcc CFLAGS='-Os -march=mips32' ./configure --whatever

As coderman noted, this might indicate a mis-compiled binary.  Make
sure you compile for MIPS32, and that you use at least gcc 3.4.4.

Upgrading to Kamikaze is good, since it will have been compiled with
a more recent release.
