Check from a command line in a working K3, see if this directory exists:
core2quad ~ $ ls -ld /proc/sys/fs/binfmt_misc
drwxr-xr-x 2 root root 0 2012-08-11 20:58 /proc/sys/fs/binfmt_misc
If not, then try:
and then check if the directory exists.
If so, we should be able to just register the uClibc loader with it for running uClibc linked programs under a glibc system.
May take a bit of experimentation to make it work.
