This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.

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.

+ * Name: pthread_barrierattr_setpshared
+ *
+ * Description:
+ *   The process-shared attribute is set to PTHREAD_PROCESS_SHARED to permit a
+ *   barrier to be operated upon by any thread that has access to the memory where
+ *   the barrier is allocated. If the process-shared attribute is
+ *   PTHREAD_PROCESS_PRIVATE, the barrier can only be operated upon by threads
+ *   created within the same process as the thread that initialized the barrier.
+ *   If threads of different processes attempt to operate on such a barrier, the
+ *   behavior is undefined. The default value of the attribute is
+ *   PTHREAD_PROCESS_PRIVATE.
+ *
+ *   Both constants PTHREAD_PROCESS_SHARED and PTHREAD_PROCESS_PRIVATE are defined
+ *   in pthread.h.
+ *
+ * Input Parameters:
+ *   attr - barrier attributes to be modified.
+ *   pshared - the new value of the pshared attribute.
+ *
+ * Returned Value:
+ *   0 (OK) on success or EINVAL if either attr is invalid or pshared is not one
+ *   of PTHREAD_PROCESS_SHARED or PTHREAD_PROCESS_PRIVATE.
+ *
+ * Assumptions:
+ *
