the problem is not that an EXTRA -rpath would probably help, the problem
is that the ld.so does not resolve an already known path.
================================================
Try1 : as you mentioned I add to Makefile.am hardcode -rapath
libtclreadline_la_LDFLAGS = -release $(MAJOR).$(MINOR).$(PATCHLEVEL)
-Wl,-rpath,$(COMPILER_NATIVE)/lib
-> this works
================================================
Try2 : as you mentioned I add to Makefile.am ld.so relative -rpath
libtclreadline_la_LDFLAGS = -release $(MAJOR).$(MINOR).$(PATCHLEVEL)
'-Wl,-rpath,$$ORIGIN/../lib'
-> this works too => partial solution
