Hi Luca, all,

I'd be happy to work on putting the changes back in 
package/bash/bash_profile.  I've only used default 
packages/configurations in Buildroot so I'm not very familiar with 
modifying them, and I could use some guidance.  Should I place 
bash_profile in package/bash and then have the bash package Makefile 
copy it to system/skeleton/etc/profile?  Or is there another way I 
should install it?
