[Buildroot] [PATCH next 0/3] dbus-python cleanup and python3 support

[Peter Korsgaard]

Hi,

This series cleans up the dbus-python package and adds python3 support. 
Doing this, I noticed that python3-config currently outputs wrong data for
--includes / --ldflags, so this gets patched as well.

There's currently (to my knowledge atleast) no other packages using this
output, so we don't need to apply it to master as well.

[Peter Korsgaard]

The patch is not needed anymore as the proper includes can be specified
using PYTHON_INCLUDES, and version/pythondir/pyexecdir is correctly detected
using host-python.

[Buildroot] [PATCH next 2/3] python3: add patch to fix --includes / --ldflags output of python3-config

[Peter Korsgaard]

The build/real prefix handling using sed breaks if build != real and the
standard include / lib directories are used ($prefix/include and $prefix/lib).

E.G.

prefix_build="/usr", libdir="$prefix/lib", includedir="$prefix/include".

If this gets installed with make DESTDIR="/foo" install, then we end up with
prefix_real = prefix = "/foo/usr" as expected, but
includedir="/foo/foo/usr/include" and libdir="/foo/foo/usr/lib" because of
the double sed invocation (prefix is already expanded).  Work around it by
ensuring we only match the beginning of the string.

Submitted upstream: http://bugs.python.org/issue22907

Thanks, series applied to next. Probably the first time that I apply
some patches from you :-)

I found one minor issue: on the last patch, you forgot to update the
dependencies of the comment, so I added the following change to your
patch:

 comment "dbus-python needs a toolchain w/ wchar, threads"
-       depends on BR2_PACKAGE_DBUS && BR2_PACKAGE_PYTHON
+       depends on BR2_PACKAGE_DBUS && (BR2_PACKAGE_PYTHON || BR2_PACKAGE_PYTHON3)

Thanks!

Thomas
