libtclreadline.so not available on ppc64el

[bugproxy]

I just found that this package is not generating the shared object for
ppc64el platform, as showed below:

  dpkg -c tcl-tclreadline_2.1.0-15_ppc64el.deb | grep lib/powerpc64le-linux-gnu
  drwxr-xr-x root/root 0 2016-10-08 05:04 ./usr/lib/powerpc64le-linux-gnu/
  -rw-r--r-- root/root 25340 2016-10-08 05:04 ./usr/lib/powerpc64le-linux-gnu/libtclreadline.a

Looking at the 'configure' process, I see the failure on detecting if
the shared object should be built. This is the build log line and
explains the problem.

  checking whether to build shared libraries... no

The real cause of this problem is realted to the following exemption of
powerpc, which might be removed.

   case "$host_cpu" in
    powerpc*) dynamic_linker=no ;
    *) dynamic_linker='Linux ld.so' ;;

With the patch above, I can see the shared objects being generated:

  dpkg -c tcl-tclreadline_2.1.0-15+deb9u1_ppc64el.deb | grep \.so
  -rw-r--r-- root/root 67664 2018-05-02 10:05 ./usr/lib/powerpc64le-linux-gnu/libtclreadline-2.1.0.so
  lrwxrwxrwx root/root 0 2018-05-02 10:05 ./usr/lib/powerpc64le-linux-gnu/libtclreadline.so -> libtclreadline-2.1.0.so

 This is being fixed in Debian already using bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=897429

this is fixed in 18.04 LTS. Is the backport to 16.04 needed?

Thanks!

>Is the backport to 16.04 needed?

18.04 was the real priority here. You can have it fixed in 16.04 if the fix is straight forward.
