Pull in missing functions for MKSOFTFLOAT.

move a COPTS setting after bsd.own.mk.

the riscv64 compat build trips on this saying:

libm: Fix arm expected symbol list harder.

LIB is not defined by the time we need it in the m.expsym rule, so
just say m here like in the other lines.

libm: Fix mips and arm expected symbol lists.

Had forgotten that they were overriding LIB_EXPSYM. Use a new
intermediate variable EXPSYM_SRC_MD for that.

libm: Factor out common expected symbol list.

Should substantially reduce the maintenance burden.

libm: Fix powerpc64 build.

- Include fenv.c and fma(3) symbols (which just use the FMADD
instruction).
- Note the .FN symbols in libm for the asm functions. The FN symbols
point at the function

libm: Fix powerpc64 build.

- Include fenv.c and fma(3) symbols (which just use the FMADD
instruction).
- Note the .FN symbols in libm for the asm functions. The FN symbols
point at the function _descriptors_; the .FN symbols point at the
first instruction of the function.

XXX Unclear why we have the .FN symbols for asm functions but not for
C functions. I'm not sure we should be exporting them.

libm: Add frexpf and frexpl on VAX.

These are trivial subroutines, not symbol aliases, for separate
reasons:

- frexpf has a different ABI from frexp (float vs double argument)

- frexp is defined i

libm: Add frexpf and frexpl on VAX.

These are trivial subroutines, not symbol aliases, for separate
reasons:

- frexpf has a different ABI from frexp (float vs double argument)

- frexp is defined in libc, not libm, so although long double is the
same as double, frexpl can't be an alias in libm of a symbol
defined in libc

libm: Split expected symbols in mips further by 32-bit vs 64-bit.

32-bit has binary64 long double, same as double; 64-bit has binary128

libm: Split expected symbols in mips further by 32-bit vs 64-bit.

32-bit has binary64 long double, same as double; 64-bit has binary128
long double, which is implemented with a few more symbols in libm
(which should maybe be hidden internal symbols, but let's get this
diagnostic measure in the build working before we think about
possibly deleting private symbols).

libm: Split expected symbols on arm and mips by hard/soft float.

libm: long double is just double on hppa, so don't use s_rintl.c.

PR misc/58054

libm: No s_rintl.c on mips32.

This is only for machines where long double is not double.

Not 100% sure this is the right criterion, but there's a good chance
it is.
