Anders Kaseorg 3cd8ce3bce treewide: Fix unsafe concatenation of $LD_LIBRARY_PATH
Naive concatenation of $LD_LIBRARY_PATH can result in an empty
colon-delimited segment; this tells glibc to load libraries from the
current directory, which is definitely wrong, and may be a security
vulnerability if the current directory is untrusted.  (See #67234, for
example.)  Fix this throughout the tree.
