[PATCH] Fix NetBSD native bootstrap

[Arnaud Lacombe <lacombar%gmail.com@localhost>]

Hi folks,

This is a third try to fix trunk native boostrap. PR concerning this issue
are summerized in PR/38182 and PR/43952.

This issue is due to several NetBSD `machine/ansi.h' (i386, amd64, as Ralf
mentionned, but also landisk, hpcsh, dreamcast and evbsh3) not defining the
expected _ANSI_H_ or _MACHINE_ANSI_H_.

For this patch I implemented Joseph S. Myers suggestion to define USER_H in
config/t-netbsd. This may be cleaner than the last patch in PR/38182 which
affect all target. In the mean time, I removed other headers the base system is
providing. stdarg.h is still needed because the host stdarg.h still reference
the old __builtin_stdarg_start(). stdfix.h is missing from the base system, so I
kept it in the include list.

Bootstrapped on i386-unknown-netbsdelf5.99.25, regression tests pending.
