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: ptsname
|
|
*
|
|
* Description:
|
|
* The ptsname() function returns the name of the slave pseudoterminal
|
|
* device corresponding to the master referred to by fd.
|
|
*
|
|
* Returned Value:
|
|
* On success, ptsname() returns a pointer to a string in static storage
|
|
* which will be overwritten by subsequent calls. This pointer must not
|
|
* be freed. On failure, NULL is returned.
|
|
*
|
|
* ENOTTY fd does not refer to a pseudoterminal master device.
