Please, use
    AC_MSG_WARN([camellia feature disabled])
or some another AC_MSG_*() macro at your taste instead of direct "echo".
"echo" doesn't handle possible descriptor's redirection in 'configure'
and doesn't duplicate message to the 'config.log'.

Second: why warning at all and not something like
    AC_MSG_CHECKING([for camelia support in libgcrypt])
    # ... actual tests here ...
    # following assumes that result stored in the shell variable
    # 'is_camelia_present' in the form 'yes' or 'no'.
    if test x$is_camelia_present = xyes
    then
        AC_MSG_RESULT([yes])
        # ... and some additional acrtions if you want
    else
        AC_MSG_RESULT([no])
        # ... and some additional acrtions if you want
    fi
