Why not take it one step further and have something like:
	..../ceph/build/{bin,sbin,lib,libexec,etc,tmp,test,log,.....}

which would be separate tree part where all the stuff is build.
Cleaning up will then also become a lot easier.... ATM the stuff in .lib
is not cleaned, I think.
It would also allow to process scripts to fit the local OS by running it
thru m4/sed/awk/perl/...

Or if you prefer so, hang it of ..../ceph/src

But then again this might require something like: make install-build
