by default since this can really make the functioning of
applications unpredictable as they can pick up arbitrary
library versions from that directory. LD_LIBRARY_PATH should only
contain very specific paths (like /var/run/opengl-driver/lib for
overriding the system OpenGL implementation, or the NSS module
path). This is even more important given that the stdenv-updates
branch uses RUNPATHs instead of RPATHs, so *all* libraries are
overridable by LD_LIBRARY_PATH.
