- Allow to build on PowerPC by using generic (not GCC-specific) MD support
  with empty machdep_init() vs. broken "Calibrating delay loop" code; some
  simple run-time tests, like booting off the kickstart ROM image, did not
  reveal any problems or performance artifacts
- Drop unsupported --enable-sound option (--with-oss-sound is the default,
  and OSS support is detected correctly)
- Remove `files/patch-configure.in' which was added in r76429 by mbr@ back
  in 2003 to allow UAE to build with GCC 3.x -- does not seem needed these
  days; consequently replace (deprecated) USE_AUTOTOOLS with GNU_CONFIGURE
- Do not patch things in `pre-configure', use `post-patch' target for that
- Sort USES values and wrap few overly long lines while I'm here
