When building host utilities, we include libfdt.h from the host, not from U-Boot. This in turn brings in libfdt_env.h from the host, which can mess up the types and cause a build failure, depending on the host environment. To fix this, force inclusion of U-Boot's libfdt_env.h so that the types are correct.
Another way to fix this is to use -nostdinc and -idirafter to ensure that system includes are included after U-Boot ones. Unfortunately this means that U-Boot's errno.h gets included instead of the system one. This in turn requires a hack to errno.h to redirect things, so all in all the solution in this patch is probably cleaner.
