For dealing with the endianess of integers the $Config{byteorder} variable available from the core Config module should be sufficient: 
    #!/usr/bin/perl -w

    use strict;
    use Config;


    if ($Config{byteorder}    == 4321)     {
        print "Big endian\n";
    }
    elsif ($Config{byteorder} == 1234)     {
        print "Little endian\n";
    }
    elsif ($Config{byteorder} == 87654321) {
        print "Cray\n";
    }
    elsif ($Config{byteorder} == 3412)     {
        print "Weird order\n";
    }
    else {
        # Not sure if it can get here
        print "Unknown byte order\n";
    }
