I think the only real way ahead with the ppoll thing is to get that
patch landed in the upstream kernel (if it isn't there already) and then
rev all the appropriate packages to include the fix.
Or, given that the syscall numbers were already reserved anyway and
hence unlikely to collide with anything else, it should be safe enough
to just apply those patches in OE. It doesn't matter that the
linux-libc-headers package is used on multiple machines: if somebody
builds against the patched linux-libc-headers and then tries to run on
an unpatched kernel, ppoll() will just return -ENOSYS which is the same
thing it would have done anyway.
