Use autoconf header detection correctly for libmissing
AC_CHECK_HEADERS already makes sure our config header contains a HAVE_$FOO_H macro if a header was found. There is no need to awkwardly set our own Automake conditionals and check for it all over the place in the Automake files. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
