Subject: Conf: Check for enabled pthreads when using BFD
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=08c1ab21a1a238054ba916011ddaada8efe8ab04;p=thirdparty%2Fbird.git

Conf: Check for enabled pthreads when using BFD

BFD protocol strictly depends on pthreads being enabled,
but the compilation configuration checks do not reflect it now.

Add a check for pthreads when BFD is included in the
configured protocols.

Thank you Alexander Zubkov <green@qrator.net> for the report and patch!

Closes: #306
