bsd-user: move arch specific defines out of elfload.c
Move the architecture specific defines to target_arch_elf.h and delete them from elfload.c. Only retain ifdefs appropriate for i386 and x86_64. Add the copyright/license comments, and guard ifdefs. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
