Printing `undefined` to stdout means that the variable is valid but not set. Instead, report an error in this case. linux 4.13 appends the result of `getconf LFS_CFLAGS` to HOSTCFLAGS, even if it prints `undefined`. This is arguably a bug in the Makefile, but even so, getconf shouldn't report that unsupported variables are valid.
