s3:build(autoconf): fix "no AC_LANG_SOURCE call detected" warnings
Autoconf 2.68 NEWS says: ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and AC_RUN_IFELSE now warn if the first argument failed to use AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have a compelling reason why you cannot use AC_LANG_SOURCE but must avoid the warning. Signed-off-by: Martin Schwenke <martin@meltin.net>
