objtool: Update sync-check.sh from perf's check-headers.sh
To allow using the -I trick that will be needed for checking the x86 insn decoder files. Without the specific -I lines we still get the same warnings as before: $ make -C tools/objtool/ clean ; make -C tools/objtool/ make: Entering directory '/home/acme/git/perf/tools/objtool' CLEAN objtool find -name '*.o' -delete -o -name '\.*.cmd' -delete -o -name '\.*.d' -delete rm -f arch/x86/inat-tables.c fixdep <SNIP> LD objtool-in.o make[1]: Leaving directory '/home/acme/git/perf/tools/objtool' Warning: Kernel ABI header at 'tools/arch/x86/include/asm/inat.h' differs from latest version at 'arch/x86/include/asm/inat.h' diff -u tools/arch/x86/include/asm/inat.h arch/x86/include/asm/inat.h Warning: Kernel ABI header at 'tools/arch/x86/include/asm/insn.h' differs from latest version at 'arch/x86/include/asm/insn.h' diff -u tools/arch/x86/include/asm/insn.h arch/x86/include/asm/insn.h Warning: Kernel ABI header at 'tools/arch/x86/lib/inat.c' differs from latest version at 'arch/x86/lib/inat.c' diff -u tools/arch/x86/lib/inat.c arch/x86/lib/inat.c Warning: Kernel ABI header at 'tools/arch/x86/lib/insn.c' differs from latest version at 'arch/x86/lib/insn.c' diff -u tools/arch/x86/lib/insn.c arch/x86/lib/insn.c /home/acme/git/perf/tools/objtool LINK objtool make: Leaving directory '/home/acme/git/perf/tools/objtool' $ The next patch will add the -I lines for those files.
