905b216648 Use __HAVE_LONG_DOUBLE instead of EXT_EXPBITS and include s_nextafterl.c 
as well as s_frexpl.c in the global list of "common" sources - as we
seem to have no arch redefining the standard double variant, it seems
unlikely we will have on redefining the long double version in assembler.

92562600d4 On alpha compile the math library with dynamic rounding mode instead 
of fixed normal IEEE rounding mode. This makes function that depends on
the current rounding mode, such as rint(3), just work.

useless notes in the latter (namely, no one cares that financial calculations
were done on Hewlett-Packard HP-71B, or that there is a LN1() in Pascal).

eb439bf1a7 Add noieee versions for lround(), lroundf(), lrint(), lrintf(), 
llrint() and llrintf().  Code copied from round(), roundf() and
rint() and modified for return values.  Its possible this may not
do the right things in edge cases, but if so its likely to have
the same issues as the existing round(), roundf() and rint().

All this used by vax (only), and should allow xnest to complete
build.

2dcdd0a999 two disgusting hacks: 
-mk/bsd.lib.mk picks up a .S asm file behind our back (did it do so
 always?). s_modf.S is incorrect; I'm undecided whether it makes sense
 to fix it, so add a stupid rule to enforce the .c file to be used.
-on i386, s_tanh.c gets miscompiled. It works with -O0, so add
 COPTS for exactly that file.

d4def06880 -build ldexp/frexp/modf locally again rather than relying on libc 
reaching over, to get things into a sane state,
-do the usual namespace protection game with scalbn(f) because it
 is used internally
(more symbol renamings are necessary)

The weak_alias change for mc68881 is untested.

d5a3d97bc4 build s_frexp.c, s_ldexp.c and s_modf.c here for new platforms, since they 
don't exist as compat functions in libc.

current list of new platforms: powerpc64.

from dennis.c.ferguson@gmail.com in PR#43042.  idea to not put compat
functions into new platforms from drochner@netbsd.

fddc3457b2 Change the use of formally undocumented features, which have now been 
made to fail.  Specifically, change
.ifdef(SYMBOL) -> .ifdef SYMBOL or .if defined(SYMBOL),
and corresponding for .ifndef.

Also correct one error in lib/libm/Makefile (.ifdef (${MKCOMPLEX} != "no")?!?).
