Yes.

Yes.  The warnings are harmless, although mildly annoying.

The issue is that GDB wants us to put that .scm file in the same
directory as libguile, in order to have GDB auto-load Guile debugging
support for executables linked with libguile.  See section 23.4.1 (The
'OBJFILE-gdb.EXT' file) in "Debugging with GDB":

  https://sourceware.org/gdb/current/onlinedocs/gdb/objfile_002dgdbdotext-file.html

Unfortunately, 'ldconfig' warns about it.  I seem to recall that we
reported the problem to the GDB developers at some point in the past.
Nowadays, most of the Guile developers seem to be using GNU Guix, where
'ldconfig' is never run, so we tend to forget about it.
