linux-user: Move elf_core_copy_regs to sh4/elfload.c
Move elf_core_copy_regs to elfload.c. Move HAVE_ELF_CORE_DUMP, ELF_NREGS, target_elf_gregset_t to target_elf.h. For now, duplicate the definitions of target_elf_greg_t and tswapreg. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
