+Nothing else uses asmjit at this time, so save on the extra library.
+(`make install` also misses installing it as a shared library.)

+- Update to new upstream release 3.7.1
+  * Expand UDMF and ZScript API for side's own additive colors
+  * Added NOFRICTION and NOFRICTIONBOUNCE actor flags
+  * Added an AMD64 JIT for DECORATE and ZScript
+  * Lights are now referenced by sections rather than surface, to
+    speed up light linking. This should allow a dynamically-lit
+    plasma bolt to pass over a 3D bridge in Frozen Time without
+    turning the game into a slide show.
+  * Add shader cache for Intel GPUs which should result in faster
+    startups.
