[oe] Enterprise kills BBMASK

[Denys Dmytriyenko]

Sorry for the "sensational" subject... :)

Basically, some time back I noticed that BBMASK stopped working. I didn't have 
time to look into it, until today. One of Mickey's commits broke the tree, 
because bunch of recipes require a missing .inc file, leading to Bitbake 
parsing failure.

Now, trying to set BBMASK leads to nothing. The problem is with 
conf/enterprise.conf, which re-sets it to empty if ENTERPRISE_DISTRO is not 
set. So, not matter what you set BBMASK to in your local.conf, it ends up 
being empty. Unfortunately, it can't be done with "+=", as it has to be a 
regular expression...

Any ideas how to fix it?
