Additionally, this: 
for ($os_arch) {
        if ("x86_64") {
                print "OS Arch x86_64 : $os_arch\n";
                $os_arch_bits = '64';
                print "OS Arch bits 1 : $os_arch_bits\n";
        }

is the same as: 

for ($os_arch) {
        if (1) {  # <------------------------------------------
                print "OS Arch x86_64 : $os_arch\n";
                $os_arch_bits = '64';
                print "OS Arch bits 1 : $os_arch_bits\n";
        }

Therefore, the 1st "if" will always be true. None of the "else" clauses will be evaluated. You don't need the for loop: 

if ($os_arch eq "x86_64") {
        print "OS Arch x86_64 : $os_arch\n";
        $os_arch_bits = '64';
        print "OS Arch bits 1 : $os_arch_bits\n";
}
elsif ($os_arch eq "i386") {
        print "OS Arch i386 : $os_arch\n";
        $os_arch_bits = '32';
        print "OS Arch bits 2 : $os_arch_bits\n";
}
elsif ($os_arch eq "i686") {
        print "OS Arch 64 : $os_arch\n";
        $os_arch_bits = '32';
        print "OS Arch bits 3 : $os_arch_bits\n";
}
else {
        print "OS Arch 64 : $os_arch\n";
        $os_arch_bits = 'XX';
        print "OS Arch bits 4 : $os_arch_bits\n";
}
