This fixes over-linking in the built Python modules with various libraries. *_LIBADD is intended for adding additional libraries for linking, while *_LDFLAGS is for miscellaneous extra flags (possibly user-supplied). If using -Wl,-as-needed within user-supplied LDFLAGS, it is passed too late (after the library link line) and therefore has no effect. Notes: * Noticed while working on Gentoo's migration to libxcrypt because libxml2's Python modules were linking to libcrypt (and other libraries) unexpectedly. * It was suggested we could actually stop linking explicitly with all of Python's libraries / don't copy its LDFLAGS, but this resolves the original issue downstream and is a separate discussion. I couldn't find any clear documentation for/against such a change. Bug: https://bugs.gentoo.org/798942 Signed-off-by: Sam James <sam@gentoo.org>
Module libxml2-python
=====================
This is the libxml2 python module, providing access to the
libxml2 and libxslt (if available) libraries. For general
informationss on those XML and XSLT libraries check their
web pages at :
http://xmlsoft.org/
and
http://xmlsoft.org/XSLT/
The latest version of the sources for this module and the
associated libraries can be found at:
ftp://xmlsoft.org/
Binaries packages of the libxml2 and libxslt libraries can
be found either on the FTP site for Linux, from external
sources linked from the web pages, or as part of your set of
packages provided with your operating system.
NOTE:
this module distribution is not the primary distribution
of the libxml2 and libxslt Python binding code, but as
the Python way of packaging those for non-Linux systems.
The main sources are the libxml2 and libxslt tar.gz found on
the site. One side effect is that the official RPM packages for
those modules are not generated from the libxml2-python
distributions but as part of the normal RPM packaging of
those two libraries.
The RPM packages can be found at:

http://rpmfind.net/linux/rpm2html/search.php?query=libxslt-python
