  From skalibs' point of view, as long as ./configure is given the
--host and --with-sysdeps options for the target, it's happy - and yes,
qemu would definitely work for generating the sysdeps.
  I've been thinking for a long time that a database of sysdeps would be
a good thing to have. If you can generate the sysdeps for all the
Buildroot targets, I'm willing to host them on for easy
global access - even though I suppose Buildroot would need to bundle
an offline copy.

  Well, cross-building is complex, so it's expected that bootstrapping a
whole cross-development environment would be heavy. But I understand
Buildroot people don't want to make execution slower than it absolutely
needs to be - and if we can have a sysdeps database, qemu at build time
is definitely not needed for skalibs.
