Clean up configure checks for OSS support. Check for the various soundcard.h headers, and then include the best one that has been found on the system. Check for definition of SNDCTL_DSP_SETFRAGMENT in those headers. Check for the correct request parameter type for ioctl(), as also modern Linux uses unsigned long. Don't list all the big endian machines (as they aren't reliable to list anyway, some of them might work with both endians), use WORDS_BIGENDIAN instead.
