Should be /tftpboot/<ip-addr>, not /root/MIPS where <ip-addr> is your
Magnum's IP address.

libc 4.6.27 is *absolutely* unusable today.  rm -rf and nothing else.
Use libc-961216.

They should all go to /usr/mipsel-linux/lib/ - and nowhere else.

Ok.

What error messages exactly?

The kernel should build where ever you install it.  But without error
messages I can't help you.
