Put the NDK library paths ahead of TARGET_GLOBAL_LD_DIRS
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.
