gcc.old: vax: mknative for PR port-vax/57646

Summary of changes:

(1) HAVE_AS_CFI_SECTIONS becomes defined.
(2) mempcpy.o is dropped as mempcpy(3) was added to -current
(but not to netbsd-10).
(3) working directories in usr.bin/gcc/arch/vax/configargs.h.

(1) will be pulled up into netbsd-10. I've confirmed that
pkgsrc/lang/perl5 builds and works as before with this change.

For now, (3) is reverted by hand. It would be better to improve mknative
not to leak working directories. But it should be NFC anyway.

For vax, mknative for binutils and gdb does not brings about significant
changes.

For other platforms, mknative for gcc.old makes no significant changes
(actually confirmed only for evbarm64, but it should be enough).

Thanks mrg@ for suggestion.

--
redo mknative-gcc for all ports. main changes include:
- "#define HAVE_CC_TLS 1" for most/all ports, thanks maya@
- "#define _GLIBCXX_HAVE_LDEXPL 1" and "#define _GLIBCXX_HAVE_TGMATH_H 1"
for many ports
- arm64 and amd64 had a broken c++config.h that disabled many things
- configargs.h has more normalisation
- ppc64 has a few things fixed, must have missed several mknative rounds
--
regen to pull out INTERNAL_CFLAGS.
--
pull -DHAVE_CC_TLS out of $(INTERNAL_CFLAGS) if it is there, and add
it to CPPFLAGS.

this fixes PR#53567 for me.
