We don't want to add RPATHS which match default linker search paths, they're

Libtool try to avoid search path used by run-time loader.
Note FSF version! Debian patched is know to be broken since decades.

There is a way to adapt old releases on Unix/Linux like build systems.
This is autoconf cache variable . I cannot remember exact name by is like 
lt_cv..dl....search...path... (1)

If I remember well libtool release 2.4.7  adds configuration variable that 
allows default search path (2) to be set.

In my cross-builds scripts I use model (1) to exclude not only path passed to 
libtool with --with-sysroot argument but additional path.

how are you defining "linker" ?  are you talking about the runtime linker
(i.e. ld.so) or the build time linker (i.e. `ld`) ?
I meant the runtime linker/loader ld.so.

the commit message also doesn't really explain in concrete details the
scenario you're running into.
We were seeing binaries with RPATHS like /usr/lib in them which
basically doesn't do anything useful since it is a default for ld.so.
We were therefore trying to remove those to improve the efficiency of
the binaries slightly.
