In autoconf v2.68, AC_LANG_PROGRAM must be quoted
This change updates the AC_LANG_PROGRAM autoconf macro invocations to be wrapped in quotes. As of autoconf version 2.68, the quotes are necessary to prevent warnings from appearing. Specifically, the autoconf v2.68 Forward Porting Notes specifies: It is important to note that you need to ensure that the call to AC_LANG_SOURCE is quoted and not expanded, otherwise that will cause the warning to appear nonetheless. Finally, because of the additional quoting we can drop the extra quotas used by the ZFS_AC_CONFIG_USER_STACK_GUARD autoconf check. Signed-off-by: Brian Behlendorf <[email protected]> Closes #464
