AC_MSG_ERROR is not suitable for config.status

[Pavel Roskin]

Hello!

The recent changes in AC_MSG_ERROR make it inappropriate for using in
config.status. There is no logfile for config.status.

Also it's better to indicate that an error happens in config.status, not
in configure.

ChangeLog:
        * acgeneral.m4 (_AC_MSG_ERROR_CS): New macro for reporting
        fatal errors from config.status.
        (_AC_OUTPUT_FILES): Use _AC_MSG_ERROR_CS.
        (_AC_OUTPUT_HEADERS): Likewise.
        (_AC_OUTPUT_LINKS): Likewise.
        * tests/semantics.m4: Updated to match error message.

Regards,
Pavel Roskin
