Hello Alexander,

these are quite normal messages when trying to cross-compile bigger 
projects.

Actually you'll find in the config.log, that the configure script tried 
to execute a programm it has recently build.
Running a mips binary on a i686 fails of course.

To fix it, you have either to hack the configure script or - better -
pre-set the variables the configure script wants to figure out.

On my arm plattform it looks like this:

export samba_cv_HAVE_MEMORY_KEYTAB=yes
export samba_cv_USE_SETEUID=no
...

Sometimes it's a bit tricky to find the right variables but searching 
the configure script for those "cannot run test program ..." is allways 
a good start.

Bye,

Martin
