## Set LD_LIBRARY_PATH
##
## On Solaris we use $ORIGIN (set in RUNPATH) instead of LD_LIBRARY_PATH 
## to locate shared libraries. 
##
## When a shared library is a symbolic link, $ORIGIN will be replaced with
## the real path (i.e., what the symbolic link points to) by the runtime
## linker.  For example, if dist/bin/libxul.so is a symbolic link to
## toolkit/library/libxul.so, $ORIGIN will be "toolkit/library" instead of "dist/bin".
## So the runtime linker will use "toolkit/library" NOT "dist/bin" to locate the
## other shared libraries that libxul.so depends on.  This only happens
## when a user (developer) tries to start firefox, thunderbird, or seamonkey
## under dist/bin. To solve the problem, we should rely on LD_LIBRARY_PATH
## to locate shared libraries.
##
## Note: 
##  We test $MOZ_DIST_BIN/*.so. If any of them is a symbolic link,
##  we need to set LD_LIBRARY_PATH.
