Python BUILDLINK_LIBDIRS

[Taylor R Campbell <riastradh%NetBSD.org@localhost>]

We install some files related to the Python build in
$PREFIX/lib/pythonX.Y/config-X.Y but then set BUILDLINK_LIBDIRS to
point at $PREFIX/lib/pythonX.Y/config.  We have done this for a long
time.

I have the attached local patch in my tree from a year ago to change
this.  I think I created it while I was trying to get devel/gdb
python3 support working, which I never finished.  I don't know what it
might matter for; evidently nobody else has tripped over it.  It is
probably needed for anything that might statically links libpython.

Does anyone want to investigate and see whether this patch is worth
keeping?  I think we should either do this or drop BUILDLINK_LIBDIRS
in lang/python*/buildlink3.mk but it's not a high priority for me,
other than cluttering up my local pkgsrc tree.

Subject: [PATCH] lang/python*: Fix BUILDLINK_LIBDIRS.

We do not install a directory lib/pythonX.Y/config.  Instead, we
install lib/pythonX.Y/config-X.Y, and we have done so for a very long
time.

This is needed in order to get at XXX something? probably something
used by the gdb python build?
