put together an ebuild for bionic, add support to crossdev to mark *-bionic targets to use the bionic ebuild, and that's about it. you could add your own KEYWORD, but doesnt seem like it'd be worth it. as for the rest, considering the fundamental limitations they've added to bionic (limited libpthreads/libm/etc...), i dont think a "full" blown port makes much sense. bionic is a toy libc meant for one thing -- get a java vm running on top of it. if you want a "real" embedded Linux system, uClibc makes a hell of a lot more sense. so feel free to put together a bionic ebuild to get into the tree, and a crossdev/toolchain.eclass patch should be trivial. -mike
