[RTnet-developers] [PATCH v2] config: Fix BS_CHECK_KHEADERS for autoconf 2.68

[Arnout V. (Essensium/Mind) <ar...@mi...>]

From: "Arnout Vandecappelle (Essensium/Mind)" <ar...@mi...>

autoconf 2.68 doesn't produce a newline at the end of AS_IF().
Therefore, whatever follows it gets concatenated with the 'fi' of AS_IF().

Removing dnl at the end of AS_IF resolves this.

Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <ar...@mi...>

Changes v2:
 * Remove dnl instead of adding extra line.
 * It's required in another place too.
 * Updated log comment.
