        src/external/gpl3/gcc: README.gcc10

Log Message:
update the status of GCC.  summary:  mostly looking good.

- all targets build or can be attempted
- arm64 needs __aarch64_swp1_acq in both libgcc and libkern
- earmv4 works, earmv7hf works, all arm32 builds, rest untested
- hppa, most/all m68k, alpha, and most ppc builds, none tested
- ia64 kernel runs as well as before, userland fails to build
- i386 runs, seems mostly fine except lib/libc/sys/t_ptrace_wait
  resume test is hung, and cpu-spinning in a zombie
- sun2 grew again, too large but builds besides RAMDISK not fitting
- mips seems problematic.  some kernels fail some work, userland
  has problems with both static and dynamic n32 and n64 programs
- sh3el seems ok in gxemul/landisk, sh3eb not tested
- vax seems OK in simh (same c++ exception issues)

all ports kernels have been tested to build (though perhaps with
some uncommited changes only needed for some, while most changes
are commited, about 15 are not but many ports build without them.)
