description:
various changes to get GCC 10 to build here.

- fix path to compiler-specific includes
- missing (void) for (older) C
- fix __is_signed/__is_signed_val change
- avoid compiler warning-as-errors
- add to existing COPTS.file values, instead of setting
- bump libgomp minor; functions were added
- add new 'compare' c++ header
- handle new analyzer subdirectory.  set TARGET_MACHINE for lto-streamer-in.c.
  remove params.list etc handling.
- coroutines.cc is another .cc not .c.  adjust .PATH to suit.
- add new lto1 sources
- couple of files not in /arch/ subdirs missed in mknative update.

rs6000.c is still not merged.
