* sysdeps/generic/bp-thunks.h: Protect includes with [!__ASSEMBLER__].
* sysdeps/unix/sysv/linux/i386/bp-thunks.h: Likewise. * sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h): Use $(make-target-directory). * sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Likewise. * Makerules (compile-mkdep-flags): New variable, pass -MD -MF $@.d. (compile-command.S): Don't use ifndef. Append $(compile-mkdep-flags). (compile-command.s, compile-command.c): Likewise. ($(objpfx)%.d): All such pattern rules removed. ($(+sysdir_pfx)sysd-rules): Don't generate them. ($(common-objpfx)dummy.d): Target removed. (make-dummy-dep): Variable removed. (generate-md5): Likewise. (%.d: %.dt): New pattern rule. (+depfiles): Use $(wildcard) function to get just existing *.d files and .d files for existing *.dt files. (common-clean): Remove all *.d and *.dt files. (before-compile): Add $(objpfx). when it doesn't exist, regardless of $(no_deps). * elf/rtld-Rules ($(objpfx)rtld-%.d): All such pattern rules removed. (rtld-depfiles): Use .os.d instead of .d names. Include existing *.d files and .d files for existing *.dt files. * Makerules ($(common-objpfx)%.make): Protect with [! subdir]. Use -MD, -MT and -MF flags instead of SUNPRO_DEPENDENCIES variable. * sysdeps/unix/Makefile ($(common-objpfx)s-%.d): Remove compat.h hack. Do s-*.d includes only if we have some syscall routines in this subdir. * include/libc-symbols.h (libc_freeres_ptr): Use %nobits instead of @nobits. The former is accepted by gas on any ELF platform.
