+
+Do not attempt to install the dynamic library when build of that library
+is disabled. Fixes the following installation error:
+
+install -m 755 lib/libi2c.so.0.1.0 .../target/usr/lib
+install: cannot stat 'lib/libi2c.so.0.1.0': No such file or directory
+lib/Module.mk:90: recipe for target 'install-lib' failed
