Bug#223604: dpkg-scanpackages: -a<arch> option causes failure with error message

[Michael Poole <mdpoole@troilus.org>]

Package: dpkg-dev
Version: 1.10.18
Severity: normal
File: /usr/bin/dpkg-scanpackages


Running "dpkg-scanpackages -ai386 pool /dev/null" generates the error
message "Binary dir -ai386 not found".  This is caused by bad indexing
of @ARGV in the script.  When processing the arguments, $ARGV[1] is
used instead of $ARGV[0]; the latter is the first argument passed on
the command line.

Even when that is fixed, it does not find Architecture: all packages
because of find's operator precedence.  This can be fixed by adding
parentheses around the -o in the $pattern variable, similar to this:
  $pattern = $arch ? "'(' -name '*_all.$ext' -o -name '*_$arch.$ext' ')'"
    : "-name '*.$ext'";
