You sample is correct .
One minor nit is AM_PROG_AR - it is not required for posted example. If 
you project requires use of this macro you should request automake 
1.11.2 as minimum.

Please check libtool achives.
To me situation on Debian is closed case.

In moment I do tests on some sources from development or stable branches 
on an another system (archaic :) ):

$ cat /etc/centos-release
CentOS release 6.10 (Final)

$ autoconf --version
autoconf (GNU Autoconf) 2.63

$ automake --version
automake (GNU automake) 1.11.1

$ libtool --version
ltmain.sh (GNU libtool) 2.2.6b

All is based on system packages except tested by me.


Result on posted test case - pass:
$ ./translib ; echo $?
12

$ readelf -a  a/.libs/liba.so  | grep RPATH
 0x000000000000000f (RPATH)              Library rpath: 
[/home/centos/.builds/test/autotools/translib/b/.libs:/tmp/translib/lib]

$ readelf -a .libs/lt-translib  | grep PATH
 0x000000000000000f (RPATH)              Library rpath: 
[/home/centos/.builds/test/autotools/translib/a/.libs:/home/centos/.builds/test/autotools/translib/b/.libs:/tmp/translib/lib]

$ readelf -a .libs/translib  | grep PATH
 0x000000000000000f (RPATH)              Library rpath: [/tmp/translib/lib]

$ readelf -a /tmp/translib/lib/liba.so | grep PATH
 0x000000000000000f (RPATH)              Library rpath: [/tmp/translib/lib]
