* The "tar-package" is used for saving the "Source" list for rpmbuild,
there is no such a file when "ARCHIVER_MODE[type] ?= srpm", and there
would be errors, it hadn't happen before was becuase that the remove
function didn't work. Let the "rpmbuild --rmsource" to remove the
Sources, and the remove function will just remove the tar-package file.
* Remove several unwanted "try ... exception" sentences, let the error
raise rather than ignore them when the error happens.
* Remove several un-needed code.
