Hi RP,

I meant that we need something to help configure the build easier, it
can generate something like local.conf.append, not configure the recipe.

The example "bitbake <recipe> -cmenuconfig" wasn't right enough, it's
just a rough thought, we can use the current default local.conf
(MACHINE = qemux86) to make system parse.

The problem is that we have many bbclasses in oe-core, a lot of them
has specify configurations, and also a lot of vars in the conf file such
as bitbake.conf, it's not easy to know how and what to config, especially,
for newbies. The "bitbake -cmenuconfig" maybe not a good idea, I think that
we need something to help config the build (generate local.conf) easier,
do you have any suggestions, please ?
