This patch in the series removing svr4.h from the headers used by
particular targets in GCC stops fr30-*-elf from using svr4.h, defining
the macros used from that header in fr30.h instead.

As with the arc patch
<http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00566.html> a simple
LIB_SPEC than that in svr4.h seemed appropriate.  The LINK_SPEC in
svr4.h also seems aimed at some non-GNU SVR4 linker and overly
complicated for any generic ELF target that will always be using the
GNU linker, and I think the simplified version here is appropriate for
such targets that have been inheriting the svr4.h definition before.

Tested building cc1 and xgcc for a cross to fr30-elf.  OK to commit?

	* config/fr30/fr30.h (LIB_SPEC, LINK_SPEC, SIZE_TYPE,
	PTRDIFF_TYPE, WCHAR_TYPE, WCHAR_TYPE_SIZE): Define.
	* config.gcc (fr30-*-elf): Don't use svr4.h.
