That is not the solution. There is a comment in lib/pt_chown.c
/* For security reasons, we try to minimize the dependencies on libraries
outside libc. This means, in particular:
- No use of gettext(), since it's usually implemented in libintl.
- No use of error() or argp, since they rely on gettext by default. */
And what you want to do, is to install libgnu.so as a shared library,
and pt_chown that links with it.
I would not do that, for security reasons.
Instead, if your main gnulib-tool invocation is with --libtool,
use gnulib-tool a second time, without --libtool and just just one
module: 'pt_chown'. This way, you can have a setuid executable that
does not link against shared libraries except libc, and it contains
the minimal needed code (basically only pt_chown.c, ptsname.c, and
ttyname_r.c).
