One could do:
BBFILES = "${OE}/org.openembedded.dev/recipes/*/${DISTRO}/*.bb"
BBFILES += "${OE}/org.openembedded.dev/recipes/*/*.bb"

Well my main concern is that the current names are kinda misleading.
I got interested in minimal (the distro) but noticed minimal-image is
not for minimal distro (as I had hoped for).
Moving the recipe to the angstrom dir makes things a little bit
cleaner, but does not resolve the name conflict

(and on a personal note: maybe 25+ angstrom recipes is a little bit
overkill, are these all actually used? )
