overuse of bitbake flags considered harmful

I was mildly amused to discover, the other day, that the output of "bitbake -e rpm | grep PACKAGECONFIG" is not quite as one might naïvely expect.

I guess the right response to this is perhaps that bitbake ought nowadays to find some other way to store its own internal state, since the idiom of using flags is pretty well established in oe-core.

p.

For those who don't realise what's going on here, the output is:

python PACKAGECONFIG () {
db bzip2 zlib beecrypt openssl libelf python}

since "python" is a flag bitbake uses to identify python functions too.

I suspect the better solution would be to use "_python" internally since we already have a convention within bitbake of prefixing internally used flags with "_".

This would mean the metadata shouldn't use that namespace but I think we can live with that.
