Do you have "." in the path (ahead of /usr/bin et al)?

If so, this will likely be the cause.  You have just built an app called 
dirname, and it exists in the current directory.  Chances are, Make is 
also using dirname to do its job.  If you have "." in the path ahead of 
/usr/bin, then the local one will be picked up.  Problem is, that's the 
MicroBlaze binary not an i386! :)

echo $PATH - tell us what you find.

As a rule, "." should never be in the path.  If you want to run a binary 
from the current directory, you should be explicit about it!  Worse, if 
. is in root's path, it's a security risk.

Regards,

John
