svr4.h avoidance: fr30

svr4.h avoidance: fr30

[Joseph S. Myers]

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?
