Mine looks similar. The reason it demands a directory is because it owns those 
files and will make changes to them during the build stages. If you want to 
make changes to the cross compiler use flags you need to make them on your own 
package.use or some other file or it will overwrite them.

Also one exception to the directory naming convention is the keywords file. The 
file was package.accept_keywords but the directory is package.keywords. IIRC 
crossdev just created that one and portage used both except for autounmask 
that kept wanting to write to the cross-* files until I moved that file. I 
always tought autounmask would write to the original package.* filename (since 
cross-* comes before package.*) until I saw Alan's reply.
