kconfig: fix return value of do_error_if()
$(error-if,...) is expanded to an empty string. Currently, it relies on eval_clause() returning xstrdup("") when all attempts for expansion fail, but the correct implementation is to make do_error_if() return xstrdup(""). Fixes: 1d6272e6fe43 ("kconfig: add 'info', 'warning-if', and 'error-if' built-in functions") Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
