The use of 'bool' data types in globally used header files cases build
errors like this:
In file included from arch/blackfin/include/asm/blackfin.h:13:0,
from include/common.h:92,
from cmd_test.c:17:
arch/blackfin/include/asm/blackfin_local.h:54:1: error: unknown type name 'bool'
Use plain 'int' instead to avoid such kind of trouble.
