CC arch/x86/decode.o arch/x86/decode.c:10:22: fatal error: asm/insn.h: No such file or directory #include ^ 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'.
