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

Browse Source 
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: unlockpt
*
* Description:
* The unlockpt() function unlocks the slave pseudoterminal device
* corresponding to the master pseudoterminal referred to by fd.
* unlockpt() must be called before opening the slave side of a
* pseudoterminal.
*
* Returned Value:
* When successful, unlockpt() returns 0. Otherwise, it returns -1 and
* sets errno appropriately.
*
* EBADF - The fd argument is not a file descriptor open for writing.
* EINVAL - The fd argument is not associated with a master
* pseudoterminal
*
