This patch implements this proposal. Only lightly tested so far. How
does this look if testing succeeds?

substitute NATIVE_SYSTEM_HEADER_DIR. Use native_system_header
when setting target_header_dir.
* config.gcc: Always set native_system_header_dir.
(*-*-gnu*): Set native_system_header_dir. Don't use t-gnu.

native_system_header_dir.
(spu-*-elf*): Set native_system_header_dir.

* cppdefault.c (STANDARD_INCLUDE_DIR): Don't define.
(NATIVE_SYSTEM_HEADER_COMPONENT): Rename from
STANDARD_INCLUDE_COMPONENT.
(cpp_include_defaults): Don't use SYSTEM_INCLUDE_DIR. Rename
STANDARD_INCLUDE_DIR to NATIVE_SYSTEM_HEADER_DIR.
* system.h: Poison SYSTEM_INCLUDE_DIR, STANDARD_INCLUDE_DIR, and
STANDARD_INCLUDE_COMPONENT.

* config/openbsd.h (INCLUDE_DEFAULTS): Change STANDARD_INCLUDE_DIR
and STANDARD_INCLUDE_COMPONENT to NATIVE_SYSTEM_HEADER_DIR and
NATIVE_SYSTME_HEADER_COMPONENT.
* doc/install.texi (Configuration): Document
--with-native-system-header-dir. Mention it in the documentation
for --with-sysroot and --with-build-sysroot.
* doc/tm.texi.in (Driver): Don't document SYSTEM_INCLUDE_DIR or
STANDARD_INCLUDE_DIR. Rename STANDARD_INCLUDE_COMPONENT to
NATIVE_SYSTEM_HEADER_COMPONENT. Rename uses of
STANDARD_INCLUDE_DIR to NATIVE_SYSTEM_HEADER_DIR.
