Comment(by leif):

 We could just always build Sage's readline and - '''before''' installing
 it - test if it works with `/bin/bash` by e.g.
 {{{
 #!sh
 if env LD_LIBRARY_PATH="." bash -c "echo 'Bash works with this version of
 readline.'"; then
     $MAKE install
     ...
 else
     echo "Bash doesn't work with Sage's version of readline - using the
 system's one."
     # Can this cause trouble with *older* system libreadlines?
     # We still need a *development* version of readline btw.
     exit 0
 fi
 }}}
