dante: Add -P to preprocessor flags

configure uses AC_PREPROC_IFELSE to check for certain errors from getaddrinfo()
it user search operation in a preprocessed file

 UNIQUEVALS=`sort $ERRVALFILE | uniq | wc -l | awk '{ print $1 }'`

However, line numbers are generated into the preprocesser files and they
get sorted higher than numbers

 gaierrval:
 # 130 "conftest.c" 3 4
           -3

-P ensures that line numbers are not generated into preprocessed files,
so these checks can succeed.
