event/octeontx2: add libatomic dependency for 32-bit clang
Checks
Commit Message
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
When compiling with clang on 32-bit platforms, we are missing
copies of 64-bit atomic functions. We can solve this by linking
against libatomic for the drivers and libs which need those
atomic ops.
