+configure: fix build on NIOS II platform
+
+NIOS II is a CPU architecture from Altera, which uses 'nios2' as the
+architecture part of the tuple. Unfortunately, 'nios2' matches the
+current '*os2*' test done by libdvdnav's configure script to detect
+the OS/2 operating system. This leads to build issues as the build
+process of libdvdnav then tries to use OS/2 specific compiler
+options, that do not exist in the gcc used for Linux/NIOS2.
+
+To fix this, this patch makes the test for OS/2 a little bit more
+specific: in the case of the OS/2 operating system, the OS part of the
+tuple contains just 'os2' (confirmed by looking at config.guess and
+config.sub in the gnuconfig project). So using '*-os2-*' will properly
+match the OS/2 operating system but not the NIOS II architecture.
+
+Upstream-status: not needed, newer upstream versions no longer have
+		 this test
