Subject: configure.in: Check the flags reported by Python.
X-Git-Tag: collectd-4.9.0~30
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=68362bd8046679278d0711c24c1c19c03f3a46a4;p=collectd.git

configure.in: Check the flags reported by Python.

On several platforms, we have observed bogus information provided by
Python. Double check those flags and only enable the Python plugin if it
is *really* possible to build anything with the library.
