Subject: event/octeontx2: add libatomic dependency for 32-bit clang
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=cea66312b4648326153a456f510fed399b5044df

event/octeontx2: add libatomic dependency for 32-bit clang

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.

Fixes: f0b9982cb3a7 ("event/octeontx2: add TIM bucket operations")
