Preserve LD_LIBRARY_PATH when using the 'env' command

In many Linux environments (and similar), just-built applications won't run
correctly without making use of the current LD_LIBRARY_PATH environmental
variable in order to find dynamic libraries. Propagate it through the 'env'
command (hopefully this works on all platforms).
