Subject: [Buildroot] [PATCH 1/1] zeromq: add libatomic linkage when available
Date: Thu, 26 Apr 2018 22:53:09 +0300	[thread overview]
Message-ID: <20180426195309.26042-1-asafka7@gmail.com> (raw)

Fixes:
http://autobuild.buildroot.net/results/ff5f7d3bcd713db9c9d92a746d6ad7134748fe16
http://autobuild.buildroot.net/results/9a743da1c3be673288c3482a9e7ddea12750206f
http://autobuild.buildroot.net/results/818b12387e6117569c4fab310b98c11fac80c047

If libatomic is available, it should be added to LIBS in CONF_ENV, since without
it we can get into a state in which symbols like __atomic_fetch_sub_4,
__atomic_compare_exchange_4 and __atomic_fetch_add_4 can't be found.
