If you look at the errors carefully, you will see that the problem is 
not in the toplevel but rather in one of the subdirectories.  So the 
problem is not ./config.cache but rather subdir/config.cache, where you 
can get subdir from the make output.  You can try deleting them one at a 
time, but if one is broken probably all are broken.  So you may want to 
try something like "rm */config.cache".

It is probably safer to just configure a new tree though.  Delete the 
old build tree and configure a new one, instead of trying to reconfigure 
a build tree after a cvs update.
