-# A list of ld library path environment variables that might need to be
-# defined.
-#
-# Some variables represent ABI-specific paths, and if these variables
-# aren't defined, the dynamic loader might fall back on a more general
-# variable. We must do the same when trying to read the current setting
-# of such a path. Each element of this list is therefore itself a list:
-# the first element of each sublist specifies the name of the variable,
-# and the other elements specify fallback alternatives. We use FOO as a
-# shorthand for { FOO }.
