Subject: [PATCH] configure: Modify ERROR to WARN for sphinx's python check
If sphinx's python version check failed, many people prefer to build
without documents instead of stopping on the error.
So this commit fixes the following:
* Modify AC_MSG_ERROR to AC_MSG_WARN
* Add clearing of SPHINXBUILD variable when check fails
