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: posix_spawn_file_actions_addclose
|
|
*
|
|
* Description:
|
|
* The posix_spawn_file_actions_addclose() function adds a close operation
|
|
* to the list of operations associated with the object referenced by
|
|
* file_actions, for subsequent use in a call to posix_spawn() or
|
|
* posix_spawnp(). The descriptor referred to by fd is closed as if
|
|
* close() had been called on it prior to the new child process starting
|
|
* execution.
|
|
*
|
|
* Input Parameters:
|
|
* file_actions - The posix_spawn_file_actions_t to append the action.
|
|
* fd - The file descriptor to be closed.
|
|
*
|
|
* Returned Value:
|
|
* On success, these functions return 0; on failure they return an error
|
|
* number from <errno.h>.
