 *thinking this scenario through*.... yes.  typically the outlier OSes
and build environments (the embedded ones).  openwrt, buildroot,
openembedded, and so on.

 emdebian is an interesting corner-case, there, which is probably
going to be adversely affected.  emdebian is unique in that it isn't a
pure from-source embedded OS, it's a half-way house between
precompiled (best of debian) and a base on which you are encouraged to
cross-compile further packages.

 unlike other scenarios (all of which are from-scratch complete source
recompiles, usually cross-compiled), emdebian _is_ going to be caught
between a rock and a hard place on that one.
