Yes and No.
For a program (like ones under tests) which is built with libtool's
-no-install option, RPATH/RUNPATH is embedded. That's true. This is
because such a program can be executed correctly with the particular
library currently being built (not with the one installed already on
With embedded RPATH/RUNPATH, such a program can be executed with no
setting of LD_LIBRARY_PATH. But, AFAIU, it is not for supporting no
setting of LD_LIBRARY_PATH.
Please note that LD_LIBRARY_PATH is usually set to run a program with
library under non-standard prefix. We can't ignore this major use case.

People would say it's a regression, I'm afraid. I think that this is a
The change of mine for minimizing library dependency has its purpose to
keep up evolusion of toolchain.
Ideally, libtool itself should have been evolved, while toolchain has
been evolved gradually.
