[PATCH] bzip2: add libbz2.so.1.0 link for compat

[<rs@ti.com>]

From: Randolph Sapp <rs@ti.com>

Add a link from libbz2.so.1.0 to libbz2.so.${PV} for compatibility with
other distributions.

A handfull of distributions are still using the "Makefile-libbz2_so" to
generate libbz2 and bzip2-shared. This creates a library with a soname
of "libbz2.so.1.0". This library link is not provide by default in
autotools builds so add one here as Gentoo does now [1].

This has been addressed upstream already, but there hasn't been a stable
release since then [2].
