This patch in the series removing svr4.h from the headers used by particular targets in GCC stops sh*-* targets from using svr4.h. The cases for these targets in config.gcc are very complicated. But the end effect as far as svr4.h is concerned is that all sh*-* targets use sh/elf.h, and those sh*-* targets using svr4.h (which is all of them except for sh*-*-netbsd*) use it immediately before sh/elf.h. sh/elf.h then overrides most of the settings from svr4.h. Thus the only setting from svr4.h which ends up being used by any affected targets is LIB_SPEC, which is only used by targets matching the first case for many targets and then not matching sh*-*-linux*, sh*-*-netbsd* or sh*-superh-elf, so ending up in the subcase *) if test x$with_newlib = xyes \ && test x$with_libgloss = xyes; then tm_file="${tm_file} sh/newlib.h" fi tm_file="${tm_file} sh/embed-elf.h" ;; and not satisfying the condition for use of sh/newlib.h. To deal with these targets I added LIB_SPEC to sh/elf.h; other targets (including sh*-*-netbsd* which did not use svr4.h) will continue to override that macro in subsequent headers as they do now. I used the same simplified generic LIB_SPEC as in <http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00566.html>; the same reasoning as there applies to the generic bare-metal targets, and for the other affected case, Symbian, empty LIB_SPEC is used on ARM so it seems doubtful the more complicated svr4.h version is appropriate for SH. Tested building cc1 and xgcc for crosses to: sh-elf sh-symbianelf sh-linux-gnu sh-netbsdelf sh-rtems sh-wrs-vxworks. (sh-symbianelf remains broken for the same reason I previously noted: "error: attempt to use poisoned "GCC_RTL_H"" and subsequent errors.)
