Subject: configure: add test for default xapian backend
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=deb4e5567c42afe834d83868b9337277256a0d66;p=notmuch.git

configure: add test for default xapian backend

This is mainly for the test suite.  We already expect the tests to be
run in the same environment as configure was run, at least to get the
name of the python interpreter. So we are not really imposing a new
restriction.
