sun4v: Split the NORMAL_GLOBALS and ALTERNATE_GLOBALS macros to _SUN4U and _SUN4V variants. Rework the return_from_trap logic to use the new variants so it is possible to use a global register as scratch register.
Move away from cubie to awin since "cubie" will actually work on non-cubie
boards.  Let the config file specify what board is being built for.
These have been moved to evbarm/awin or conf/*.awin
Remove (now duplicated) target computation.
Add Samsung Electronics XP941 M.2 SSD
Regen.
The t_ldp_regen test frequently fails under qemu, but reliably passes
on real hardware.  The failures are hardly surprising given that qemu
timing is off by a is off by a factor of two as reported in
PR kern/43997.  Disabling the test on qemu for now; it should be
re-enabled once 43997 has been fixed to see if it still fails then.

Make random.S invisible for coldfire too (e.g. anything not "m68k")
float32_is_signalling_nan needs a prototype if SOFTFLOATM68K_FOR_GCC is
defined.
Add a slightly stripped down version of sys/dev/clock/clock_subr.h to make
this code available for tools.
Reformulate an overflow test so it can be used in tool builds (i.e. does
not depend on netbsd specific macros).
Avoid trigraphs
Make msdosfs time conversion use the y/m/d/h/m/s conversion functions
from clock_subr.c and compile that into the userland (and tools)
makefs as well.
Copy definitions of __type_min(t), __type_max(t), and some related macros,
from <sys/cdefs.h>, for use when building tools.
Revert previous; test secs > __type_max(time_t) again, now
that __type_max is available in tools/compat/compat_defs.h.
If HAVE_NBTOOL_CONFIG_H is set, then include "nbtool_config.h",
because this file is compiled as part of tools/makefs.
Increase the `freqbuf' buffer that holds the result of humanize_number(). Now
it prints 1600 Mhz instead of 1 Ghz.
Pitty enough humanize_number(9) doesn't do 1.6 Ghz type output.
Add tools/README, to collect hints like how to use

.if defined(HOSTPROG)

and

#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif /* HAVE_NBTOOL_CONFIG_H */
Update the cycle counter i.e. our CPU frequency for all CPUs on setting the
cpu frequency.
