A name of a cache directory produced by the compiler for a library is
based on the unique name of this library. The cache task, when
declaring its outputs, assumes that this unique name is equal to the
name of the library file/directory. If this is not the case, the
up-to-date check works inconsistently and Gradle doesn't rerun
the task.
This patch fixes this issue by obtaining the real unique name of
the library.
