+osdep.m4: Remove getaddrinfo() too low checks
+
+dante runs AC_PREPROC_IFELSE then it fills $ERRVALFILE by running the
+following command:
+
+cat conftest.i | grep gaierrval: >>$2
+
+As a result, $ERRVALFILE does not contain the expected values because
+the expected value is not on the same line than gaierrval:
+
+ gaierrval: 
+ # 130 "conftest.c" 3 4
+           -3
+
+So drop these checks
