+- Switch to git checkout (GitHub tarbals lack required submodules)
+- Build unit tests separately as they impact the build result and
+  produce a broken install rule
+- Update to version 2.9.2:
+  * colorspace: fix crash on invalid conversion from unspec to
+    real primaries
+  * x86: additional optimizations for AMD Piledriver
+  * x86: optimizations for AMD Zen2 processors
