1Remove dependency on dpkg

3Upstream-Status Submitted

5Asking the host OS whether it supports multiarch is not useful
6in a cross-compilation environment, or if the user has specified
7a libdir explicitly. So this patch, based on the work of Mentor
8Graphics, removes mklibs's dependency on dpkg package.

4Subject: [PATCH] Show GNU unique symbols as provided symbols
5
6Upstream-Status Submitted
7
8GNU Unique symbol is a GNU extension employed by new version of GCC
9by default. Even Standard C++ library in GCC 4.9 provides some symbols,
10such as _ZNSs4_Rep20_S_empty_rep_storageE in this binding type instead
11of ELF standard weak binding.
12This patch adds support of this new binding type to mklibs-readelf.
