This replaces the AC_MSG_ERROR with AC_MSG_FAILURE, where appropriate.
The AC_MSG_ERROR outputs given message and exits the configure step. The AC_MSG_FAILURE does the same but also automatically outputs additional message "See 'config.log' for more details." which might help directing the user where to look further.
The AC_MSG_ERROR is used for errors where current test step isn't logged in the config.log and wouldn't make sense, and AC_MSG_FAILURE is mostly used in cases of library checks, compilation tests, headers checked with AC_CHECK_HEADER* and similar tests that are also logged in the config.log.
AC_MSG_ERROR([Sanity check failed.]) output:
AC_MSG_FAILURE([Sanity check failed.]) output:
