I'm working on a similar problem
(http://autobuild.buildroot.net/results/dd0/dd04833b11a0ebb0193c861cb375b2112dd339d1/).
The following configure log shows the problem:
checking for a Python interpreter with version >= 2.6... python
checking for python... /usr/bin/python
checking for python version... 2.6
The host packaged python (2.6) is detected instead of the buildroot built one
(2.7), because the python symlink is missing. In this case
BR2_PACKAGE_PYTHON3=y so even with this patch the problem is not fixed. Your
commit e1584b7d3350 (python: rework python symlinks installation) originally
limited host python symlink creation, but I could not understand the reason
for this from the commit log.
