[PATCH 1/2] Show GNU unique symbols as provided symbols

[<rongqing.li@windriver.com>]

From: Yuanjie Huang <yuanjie.huang@windriver.com>

GNU Unique symbol is a GNU extension employed by new version of GCC
by default. Even Standard C++ library in GCC 4.9 provides some symbols,
such as _ZNSs4_Rep20_S_empty_rep_storageE in this binding type instead
of ELF standard weak binding.
This patch adds support of this new binding type to mklibs-readelf.

Hi maintainers:

I have two patches for mklibs, but I did not find the maillist for mklibs,
so send them to you, hope you can review them, thanks.
