To avoid race condition: Say a module with LOCAL_NDK_VERSION built in the full source tree, Before this change it may be linked against TARGET_GLOBAL_LD_DIRS/libc.so that's being partially written out by the linker, because there is no dependency between the module and TARGET_GLOBAL_LD_DIRS/libc.so.
