Subject: Fixing find_library() on POSIX-like (excluding Darwin) systems.

This isn't addressing Python's wrapper for dlopen(3).

This possibily addresses mostly NetBSD as other popular OSes have ldconfig.

Testing commands:

 - before applying the patch

>>> from ctypes.util import find_library
>>> find_library("m")
'libm.so.0'
>>> find_library("crypto")
'libcrypto.so.11'
>>> find_library("GL")
>>> find_library("curl")

 - after applying the patch

>>> from ctypes.util import find_library
>>> find_library("m")
'libm.so.0'
>>> find_library("crypto")
'libcrypto.so.11'
>>> find_library("GL")
'libGL.so.2'
>>> find_library("curl")
'libcurl.so.4'

This patch doesn't solve the case of custom dirs like $PREFIX/qt5/lib.
However it's solving most common cases of using this call.

A possible solution is to parse the output "pkg_info -La"... however it's
very slow. In other words a cache with libraries might be needed to handle
it efficiently.

Bump PKGREVISION.
