Sometimes genkernel generates an empty linuxrc inside initrd. This renders the 
initrd unusable. 
 
I attach a patch to fix the problem. 

Reproducible: Sometimes
Steps to Reproduce:
1. run genkernel 
2. mount the generated initrd 
3. check the file linuxrc 
Actual Results:  
The file linuxrc has size 0 

Expected Results:  
The linuxrc should contain a script

the last one doing the >
