* Makerules: Always use -MP together with -MD. (sed-remove-dotot): Substitute $(..) also at start of line. ($(stdio_lim:h=st)): Use -MD instead of SUNPRO_DEPENDENCIES. Generated defines with a single compiler call. Use $(sed-remove-dotdot). * mach/Makefile ($(objpfx)mach-syscalls.mk): Use -MD instead of DEPENDENCIES_OUTPUT, and use $(sed-remove-objpfx). * sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h): Use -MD instead of SUNPRO_DEPENDENCIES, and use $(sed-remove-objpfx). * sysdeps/unix/sysv/linux/mips/Makefile ($(objpfx)syscall-%.h): Likewise.
