buildspec.mk TARGET_STRIP := 1

Another important change I forgot to mention.
In froyo-x86, you may know you could get a smaller
image (strips all debugging symbols) by adding
TARGET_STRIP := 1

In gingerbread-x86, the debugging symbols are stripped
by default, so no need to use this variable anymore.
Actually the AOSP has used the variable for a
different meaning. Make sure you remove it
from your buildspec.mk.
