* configure.in: New check for -g on .S files. * configure: Regenerated. * config.make.in (have-cpp-asm-debuginfo): New variable. * config.h.in (HAVE_CPP_ASM_DEBUGINFO): New #undef. * Makeconfig (ASFLAGS): New variable, if undefined and $(have-cpp-asm-debuginfo), take options matching -g% from $(CFLAGS). * Makerules (compile.S, COMPILE.S): Use $(ASFLAGS).
