The standard build system does not provide an easy way to do this.  If you
are using petsc-dev, you use CMake (configure as usual, but then run make
from $PETSC_DIR/$PETSC_ARCH instead of from $PETSC_DIR).  The CMake build
files default to setting RPATH, but it is easy to set the cache variables to
disable RPATH.
