Thanx!
I will submit patches (with a hope and prayer that they get committed
before I do -- which might to be too long now) :-)

Notice the "/usr/bin/mipsel-linux-uclibc-objdump: Can't disassemble for
architecture UNKNOWN!" above. It was a small problem in my ksymoops
cross-build, but to remedy it (the build error is fixed of course) I
have done:
$ ls -l /usr/bin/mipsel-linux-uclibc-objdump
lrwxrwxrwx 1 root root 86 2008-10-17 07:27 /usr/bin/mipsel-linux-uclibc-objdump
->
/usr/src/openwrt/staging_dir/toolchain-mipsel_gcc4.1.2/bin/mipsel-linux-uclibc-objdump
$ ls -lL /usr/bin/mipsel-linux-uclibc-objdump
-rwxr-xr-x 2 brian brian 381228 2008-10-16 19:14
/usr/bin/mipsel-linux-uclibc-objdump
So that shouldn't be the problem. Maybe my cross-build was not
successful.
