objtool: Fix ARCH=x86_64 build error
Building objtool with ARCH=x86_64 fails with:
$make ARCH=x86_64 -C tools/objtool
...
CC arch/x86/decode.o
arch/x86/decode.c:10:22: fatal error: asm/insn.h: No such file or directory
#include <asm/insn.h>
^
compilation terminated.
mv: cannot stat ‘arch/x86/.decode.o.tmp’: No such file or directory
make[2]: *** [arch/x86/decode.o] Error 1
...
The root cause is that the command-line variable 'ARCH' cannot be
overridden. It can be replaced by 'SRCARCH', which is defined in
'tools/scripts/Makefile.arch'.
