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 libdvdread's configure script to detect the OS/2 operating system. This leads to build issues as the build process of libdvdread 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.
