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.

*
|
|
* Description:
|
|
* fgets() reads in at most one less than 'buflen' characters from stream
|
|
* and stores them into the buffer pointed to by 'buf'. Reading stops after
|
|
* an EOF or a newline. If a newline is read, it is stored into the
|
|
* buffer. A null terminator is stored after the last character in the
|
|
* buffer.
