[PATCH] insane: Add mechanism to extend QA machine information from BSP layer

[Richard Purdie <richard.purdie@linuxfoundation.org>]

In order to add a new architecture or sub-architecture to OE, you currently
need to tweak the table in insane.bbclass. This adds a mechanism so this
can be done from a BSP layer. It needs a function definition which needs
a class file but can then be done with something like:

def my_testfunc(machdata, d):
    machdata["testmachine"] = {
                        "test64":       ( 8,     0,    0,          False,         32),
                        "testel":     ( 8,     0,    0,          True,          32),
                      }
    return machdata

PACKAGEQA_EXTRA_MACHDEFFUNCS = "my_testfunc"
