On my Linux machine when i run 

```
uname -v

```

```

Now i am building my custom kernel and i need to show some flag/text info about build in this string ..

i want something like
if some config are on then add `BUILD-XYZ` in that string

```
   #83-Ubuntu SMP Wed Jan 4 11:12:07 UTC 2012 BUILD-XYZ

```

if not then add `BUILD-ABC` in that.

```
  #83-Ubuntu SMP Wed Jan 4 11:12:07 UTC 2012 BUILD-ABC

```
