$(block-obj-y) pulls in 'aio.o' which is built from aio.c which

for libs/apps since it is incompatible with both LGPLv2(+) and GPLv3.
Now in this case aio.c is labelled as Copyright IBM / Anthony,
so IBM could likely resolve this licensing to be more widely
compatible. This could^H^Hwould become a non-trivial task if we
need to look at many files& then also any patches accepted to
those files from 3rd parties over the years :-(
If there was a block driver library, I would expect it to be GPL, not LGPL.
This would prevent us from using it in libvirt, unless we wrote a
helper program which we spawned anytime we wanted to use some
functionality library :-(
