$NetBSD: patch-Lib_distutils_command_install__egg__info.py,v 1.2 2020/08/22 13:01:42 schmonz Exp $

On systems where both of the conditions

1. LD_LIBRARY_PATH does _not_ take precedence over DT_RPATH
   (e.g. Linux)
2. A previous libpython with the same major.minor is already installed
   (e.g. a previous version of this package)

hold, the built python will be linked with the installed libpython,
causing it to report an old teeny version in
self.distribution.get_version() while staging the install. Then "make
package" fails with PLIST mismatches for Python-2.7.XX-py2.7.egg-info.

pkgsrc knows which version we're building. Pass that down instead.

In patch-Lib_distutils_unixccompiler.py, we override Python maintainers'
expectations for Linux builds in favor of pkgsrc's expectations for
builds on all platforms. This patch is needed because of that patch.
