In some build configurations, the target we depend on is not available for declaring the build dependency. We only need to declare the build dependency, if the build target is available in the same build. Fixes the issue raised in https://reviews.llvm.org/D107156#2969862 This patch should go into release/13 together with D108404 Differential Revision: https://reviews.llvm.org/D108868 (cherry picked from commit 5ea1c37118699f0ed1da17e0d8562011d0002edd)
