Now configure will set -march=i486 and -mcpu=i686, which I suppose was
your intention. It compiles and runs fine now.

There is one thing though:
"Compiled with RUNTIME CPU Detection - warning, it's not optimal! To get
best performance, recompile mplayer from sources with
--disable-runtime-cpudetection"
Does this mean that my current configuration should not use
runtime-detection, or is that a general hint now?

Also attached the output from a 'cat /usr/compat/linux/proc/cpuinfo', at
your request. Have fun with it :)
