;;; We must re-enable ldconfig in glibc for Steam to prefer our system libraries
;;; over Steam's runtime (which has incompatible Mesa and gcc). This is because
;;; the Steam script located at
;;; Steam/ubuntu12_32/steam-runtime/run.sh
;;; overrides $LD_LIBRARY_PATH with the following order enforced:
;;; * "Pinned" libraries (pinned_libs_{32,64} directories containing symlinks)
;;; * Output from `/sbin/ldconfig -XNv`
;;; * steam-runtime paths
;;; * Existing $LD_LIBRARY_PATH
;;; Without ldconfig Steam's runtime will have priority over system libraries as
;;; well as any paths supplied to Steam in the initial $LD_LIBRARY_PATH.
;;; "Pinned" library directories are created after installation, so we can't
;;; use those either.
;;; Disabling Steam's runtime is another solution, however that will add over
;;; 80 additional dependencies (see commit: @a12f42e6)
