This patch in the series removing svr4.h from the headers used by
particular targets in GCC stops sparc*-* targets from using svr4.h.

There are eleven config.gcc stanzas involved here, every SPARC stanza
apart from sparc64-*-freebsd*|ultrasparc-*-freebsd*.  All SPARC
stanzas use sparc/sysv4.h, after svr4.h for all those using svr4.h.
That overrides three of the macros from svr4.h (ASM_SPEC, SIZE_TYPE,
PTRDIFF_TYPE).  The remaining macros from svr4.h all end up overridden
by one header or another for all eleven stanzas, so all this patch
needs to do is change config.gcc without any changes needed to the
configuration headers themselves.

Tested building cc1 and xgcc for crosses to: sparc-elf sparc-rtems
sparc-linux-gnu sparc-netbsdelf sparc-sun-solaris2.10
sparc-wrs-vxworks sparc64-elf sparc64-rtems sparc64-linux-gnu
sparc64-netbsdelf sparc64-openbsd.  OK to commit?

	* config.gcc (sparc-*-elf*, sparc-*-rtems*, sparc-*-linux*,
	sparc-*-netbsdelf*, sparc*-*-solaris2*, sparc-wrs-vxworks,
	sparc64-*-elf*, sparc64-*-rtems*, sparc64-*-linux*,
	sparc64-*-netbsd*, sparc64-*-openbsd*): Don't use svr4.h.

This looks good to me.
