Yeah, ccache has been around a while. It's sometimes a big win on
compiling things.

You can do: 

rpm -e ccache --test

and see if there is any dependency that won't let you remove it. 

You can look at your /var/log/messages and yum should have logged what
package set it was installed with, which might tell you the package
that needs it. 

You can do 'yum install yum-utils' and then: 
repoquery -a --whatrequires ccache

(off hand I don't see anything that requires ccache... )
