+From 7652931d33b36c93b2e84713baa8c283d568402e Mon Sep 17 00:00:00 2001

+Subject: [PATCH] meson: link gallium nine with pthreads
+
+In some cases (not building with llvm, which automatically pulls in
+pthreads) nine needs to be directly linked with pthreads. Fixes building
+on x86 (32 bit) without llvm.
+
+Distro bug: https://bugs.gentoo.org/670094
+Fixes: 6b4c7047d57178d3362a710ad503057c6a582ca3
+       ("meson: build gallium nine state_tracker")
