# placing it right after the LD_PRELOADs. This is used to compensate for the fact
# that Android linker does not look at the dependencies of the main executable
# that aren't dependencies of the current DSO when resolving symbols from said DSO.
# As a net result, this allows running ASan executables without LD_PRELOAD-ing the
# ASan runtime library.
