At the very least, /usr/include/apr-1.0/apr.h is arch dependent and 
would have to be moved.

/usr/share/apr-1.0/build/apr_rules.mk is also generated during build and 
could therefore also differ between architectures. I think it would take 
some effort to figure out if this can be safely shared or how one could 
make sure that the correct version is used.
