Squashed commit of the following: libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected). libs/: Fix paths in moved library directories. libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
