[vlc-devel] [PATCH 02/15] nacl: Add new system type

[Julian Scheel]

Add system type for Google (Portable) Native Client. As Portable Native
Clients do not allow dynamic library loading the plugin loader is
worthless and thus replaced by a dummy stub.
As newlib does not provide strerror_l the existing replacement from
android platform is used.
