The libtool.1 man page embeds the build path as it includes the compiler
flags, -fdebug-prefix-map (which is used by default in dpkg) or
-ffile-prefix-map (an optional dpkg feature, enabled in
tests.reproducible-builds.org for testing packages from unstable and
experimental), and both pass the full build path as part of their
arguments, resulting in a differing build dependding on the build path.
The attached patch removes the -fdebug-prefix-map and -ffile-prefix-map
arguments from the libtool.1 man page.
Thanks for maintaining libtool!
With this patch and the patch just submitted in #949270, this
should be reproducible in tests.reproducible-builds.org!

p.s. The most recent versions of libtool uploaded to the archive are not
present in the salsa git repository; it would be nice to fix that.

Subject: [PATCH 2/2] debian/rules: Remove file-prefix-map/debug-prefix-map
arguments from the libtool.1 manpage, which results in an unreproducible
package when the build path varies.
