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. Signed-off-by: Anders Kaseorg <andersk@mit.edu>

# For a 64bit + 32bit system the LD_LIBRARY_PATH must contain both the 32bit and 64bit primus
|
|
# libraries. Providing a different primusrun for each architecture will not work as expected. EG:
|
|
# Using steam under wine can involve both 32bit and 64bit process. All of which inherit the
|
|
# same LD_LIBRARY_PATH.
|
|
# Other distributions do the same.
