Comment(by vbraun):
I'm still trying to solve one issue with the rpaths. The problem is that
Sage does not distinguish build preparation (configure) from the actual
build. If we set relative rpaths, then configure requires LD_LIBRARY_PATH
set because the configure scripts will build and execute binaries in
random directories in order to test prerequisites. If we had separate
prepare/build phases, then we could run configure with absolute rpaths and
then switch to relative rpaths for the final build.
The problem with LD_LIBRARY_PATH is, of course, that sometimes it screws
up parts of the toolchain. We had that with GMP/MPIR before, and now PPL.
