Bug#623484: dpkg-cross doesn't detect libs not directly under /usr/lib

[Andre Kostur <akostur@incognito.com>]

Package: dpkg-cross
Version: 2.5.8
Severity: normal

Certain packages have libraries that exist in a subdirectory under /usr/lib.
dpkg-cross fails to detect these as valid libs to include.  A specific example
is libaxis2c0_1.6.0-1_amd64.deb.   I'm trying to repackage this for use on
an i686 machine.  This package supplies a set of shared
objects under /usr/lib/axis2/lib.  However, running dpkg-cross against this
package results in "package libaxis2c0 doesn't provide any useful files.
Skipping."

Perhaps dpkg-cross should either be able to find libraries in subdirectories
of /usr/lib, or the user could supply additional paths to look for libs?

# you can set the following variables here:

$(DEB_HOST_GNU_SYSTEM)-
#  crossbase  : base prefix for the following; default: /usr
#  crossdir   : base directory for architecture; default:

#               dpkg-buildpackage will use the name from the
#               changelog, too, but signing the .changes will be done
#               as the current user (default key).
